And here we have th' Lord of Valve demonstrating once again what a dick
he is. More useless BS, right Caraudiomikehuntdicklessguy?
BTW, Lord, didn't I read that the Mho was renamed the Seimans? No, I am

Thanks for the review.
Everything you need to know to operate the Maxi-Matcher is
printed right on the front panel. There's a chart (all the
graphics are nicely silk-screened in a tasty maroon color,
against a cream white background) which lists the tube types,
and details the settings necessary to test each type.
There are also some "acceptable" current and transconductance
ranges listed, which I don't entirely agree with. (I think
that the folks who developed the Maxi really didn't have
enough representative examples on hand of all the different
tubes listed when they were brainstorming the device, since
I've found many tubes in the course of the matching process
which fell outside the listed ranges and still performed
flawlessly when installed in actual guitar amps.)
Tube types listed on the front panel are 6L6, 5881, EL34,
6550, EL84, 7027, and 6V6. There are four rotary switches,
a rocker-type power switch, and a 4-digit LED readout with
LARGE characters (5/8" tall) that can be easily read even
under bright lights. Two plate voltages are available:
400 and 325, selected by a rotary switch (which also has
an "off" position.) 5 bias voltages (-60, -48, -36, -24,
and -12) are selected by another rotary switch; this one
(understandably) has no "off" position. Two more rotaries
round out the control compliment; one selects test sockets
one through four, and the other switches the LED display
between the plate current and transconductance readings. All
of the switches have that really positive "snappy" feel that
goes with quality test gear. (This gizmo ain't cheap...
$500, and the EL84 adaptors are extra, too...) Plate current
is displayed in milliamps, with one digit to the right of the
decimal point. Of course, even with well-warmed-up tubes,
there is considerable last-digit jitter; for matching purposes,
however, this is not a problem. (The difference between 20.5
mA and 20.9 mA is completely inconsequential, in any amplifier
you're likely to run into.) Transconductance is displayed in
"Deci-mhos," which (I think) is Allen Kaatz's way of saying
"We put the decimal point in a strange place, for some reason."
Again, this doesn't matter, for matching purposes...2.37
decimhos is every bit as useful a figure as 2370 micromhos.
(At least, I *think* that's how it works out...) Again, there
is some last-digit jitter when taking this reading.
When screening a whole pile of 'raw' tubes, it's always a given
that a few will be defective; the Maxi-Matcher has a slick
way of dealing with this...a circuit they call a "Smart Fuse"
will shut down the plate supply if the current rises above
140 mA. A red LED lights up when this happens. "Remove
bad tube to reset" is the marking by this LED; in actual use,
I found the circuit to be a little on the ambitious side. It
occasionally activates when switching from one test socket to
another; possibly a transient is generated during switching
which 'fools' the circuit into thinking a short exists. It
works just fine when you smack a tube to test for shorts,
though...instead of blowing the HT fuse or smoking a screen
resistor (like my homebrew modified Laney chassis does) when
a tube croaks, it just lights up the protect LED. Nifty!
One of the five octal sockets is marked "Short Circuit Test,"
and it has two red LEDs which will light (or just one of them,
depending on what's shorted inside the tube) when a shorted
tube is plugged in. The one-page dopesheet that comes with
the Maxi doesn't state which leakage paths are actually tested
by this socket, but it does say that it checks for leakage of
"up to 10 K-ohms resistance."
In actual use, I found that I preferred to test Tesla 6L6s
and Sovtek 5881s with a bias voltage of -36 rather than the
specified -48, as the current readings I was obtaining with
the higher bias were all rather low. I prefer to stress the
tubes a bit when I'm testing, anyway...after all, the guys
who buy 'em are gonna thrash the crap out of 'em, right?
On the other hand, NOS Philips 7581As, Svetlana 6L6GCs, and
the new Sovtek 6L6WXT+ all gave usable readings with the
bias set to -48. ALL the 6550s (NOS GE, Svetlanas, old
Sovteks, and the new Sovtek 6550WE) liked the specified -48
bias voltage, and all of the other types listed on the front
panel tested best with the recommended settings. The 'factory'
specs listed for the various types were 400 volts plate (with
the exception of the EL84, specified at 325) and the following
bias voltages were recommended: 6L6 = -48, 5881 = -48, EL34
= -36, 6550 = -48, EL84 = -12, 7027 = -48, and 6V6 = -36.
I took the bottom plate off (a fairly thick steel piece) for
a peek under the hood; I found a double-sided hand-soldered
PCB, with the parts accessible without board removal. Aside
from the 40-pin (or so) display-driver chip, nothing strange
presented itself...a couple of TO-220 stye regulators, a few
diodes, an IRF380 mosfet power transistor, an LF-353 opamp,
and an RC4558. Four trimmers, all unmarked. The usual
resistors and caps. I only saw one 'added' (tack-soldered)
capacitor, so the board was evidently well thought out before
it went into production. The sockets appear to be first-rate
parts; it does look like it'll be a bit of a job to replace
them when the time comes, though. Overall, the Maxi is built
like a tank. HOWEVER...
Lord Valve Bitcheth:
Yeah, I got a bitch...the HV and bias supplies are UNREGULATED.
This puts the test readings at the mercy of line fluctuations.
Allen says they will offer an upgrade for the older units (and
a factory-installed option for the newer ones) which will
include regulated supplies. For now, I have to "ride gain" on
my Variac, making sure that the incoming AC line is dead-on
120 VAC. (I've got one of my Flukes set up to monitor the line,
where I can see it easily.) Since I had to do this with my old
rig, I'm used to the procedure...but I'll sure be glad when the
upgrade is available. Mr. Kaatz mentioned that the folks at
Vacuum Tube Valley tested some of the unregulated units, and
that they "didn't find this to be a problem." Perhaps they
don't match 'em as tightly as I do...or perhaps they didn't
consider that one might need to match tubes from a new batch
to some from the last batch...three months later, when the AC
line is 5 volts lower or 3 volts higher. At any rate, this is
a shortcoming that I can deal with (for now) while I wait for
the upgrade to come online.
The Nitty-Gritty:
At $500 a crack (plus an estimated $150 for the regulated HV
supply upgrade, plus whatever adaptors may be required) this
is not a toy for the hobbyist or amateur tech. For a high-end
audio shop, or a small tube-supplier like me, it's the best
damn thing since sliced bread. Larger tech shops might want
to own this, too...buying tubes in bulk and saving the matching
fees will pay for this unit quickly. BTW, there is also a
larger unit available that loads 25 tubes at a time...but it
gives only current readings and no transconductance info.
Bottom line: I LOVE MY MAXI-MATCHER!! And, no...I don't get
a nickle if you buy one...I hadda pay for mine like any other
slob. Dammit. :)

I'm a little surprised that there are no chokes or tranny's (output
load) in there. I contemplated building one of these (without the
digital part) and realized (incorrectly?) that using resistive plate
loads (with load values like 5K or so) would create such voltage drops
that the plate voltages would be way lower than desired (eg. 400VB+ -
(50mA X 5K= 150V). Hmmm, could this mean that B+ is WAY up there? Or
does it mean that the plate load resistances are very low? Does it mean
I have no idea what I'm talking about? (most likely! :-)
Anyway, mine wouldn't have had the Gm measurement in it so I'd still be
doing a 2 stage matching process (using a tube tester to measure Gm).
If you dial in the variac closely, are your day to day readings pretty
repeatable?
Thanks for the great review!

I can emphasize with you on this one. I have diabetes on both sides of
my family; so, I have had to watch my weight for the better part of the
thirty-seven and half years I have been on the face of the Earth. There
is nothing like watching a member of one's extended family have their
legs amputated, because of lack of circulation, to motivate one to
exercise and watch their weight. My mom is a type II, insulin-taking
diabetic (my grandmother was also, and died from a toxic reaction to
insulin), and has lost quite a bit of feeling in her hands and feet.
All I can say is to take it one day at time. In time, you will adjust
to your new diet. I also recommend that you try to get one hour of
physical exercise (walking is fine) in three times a week.
Take care of yourself diabetes is a serious problem!

Really sorry to hear that. Best of luck with it. (24 pounds
is pretty impressive. Good on you .. er .. I mean good off you).

Agreed, I test 'em at 400V HT & 30V bias
on my AVO. (Cost me 20 quid, courtesy of HM

Actually, you have to be careful with sun tea. I just heard the other

this way (even in Arizona!!!).

Does this mean that we'll have to call you "Skinny Willie?" :-) I am sorry

Same here...throw some round Tetley teabags in a jug o' hot water,
put it in the fridge for a few hours.
Tea that's sat in the sun too long tastyes sour, anyway.
And tea or coffee made with water that's too alkali tastes like crap.
>And you thought I just made beer!
And you thought I just *drank* it..
wheeeellll then...
as I hear it... a simple... ugh solid state circuit could be devised
in a neat little package to constantly monitor and adjust the line
voltage... sooo how do we do this??? what we really want is a little
troll to sit and watch our variac out and constantly adjust it so it
is null...but alas trolls requre hourly wage.. and still spend 90% of
their time neglecting their work to surf....
in any event... aside from implamentation... how hard would it be to
connect a bigass variac to geared motor and then to a simple
adjustment circuit to provide the nuts on 117V???
a good friend asked me about such a circuit... the bigass variac being
the key... since this was for a delicate tubed circuit... and even the
shift of a couple line volts changed his art to something arcane...
I agree with the bigger the variac the less it effects my sound... and
suggested the actual driving circut would be simple, but the putting
in a box would suck...
I have seen the switched tap autoformers... they are good.. but how
about one step better???
who knows maybe the switched ones...even at 2V incraments... will
sound better than a wiper at the precise voltage...
i understand several cans o worms have been mentioned... personally I
find it hard to swallow that 2V in line variation will ever be an
issue.. (sound..not safety wise) but then again...

Weel, Lord Valve, if you had bothered to read *his* post, you would see how
off base your complaint is. In fact, what he was discussing has everything
to do with tight line voltage regulation, which BTW is NOT EVEN the subject
of this thread (refer to subject line for clarification). So, YOU are just
as off topic as he is in the context of the original thread, but when you
shift the context to the latter voltage regulation discussion, he is right
on the mark, regardless of what type of equipment he was stating he had
experience in using with a variac.
>try *reading* the post, instead of

Honestly. What a bunch of shit. You do realize that your post could not be
more textbook an example of a knee-jerk reaction, don't you? I'll bet your
knee isn't the only thing you...... Never mind......
Why are you so eager to show your ass and be rude and condescending to a
person who just contributed to a thread you appear to have an interest in?
Do you feel yourself to be so superior that other people's suggestions can
be written off with such a smug stroke of the pen? If so, whose posts do
you read here, your own? Or mabye it's just that we neophytes have
absoutlely nothing that could be of any possible use to 'Lord Valve', who is
the sole keeper of all that is right and good....
If you guys are after clean line power, shit go down to the computer store
and buy yourself an APC Smart-UPS and run everything off it. Pure sine wave
output, shitloads of filtering, and real-time voltage regulation even if the
line voltage is +/- 15 volts of normal. And if you get a bad brownout, or
worse blackout, *click* over to battery mode. I run my entire system of a
Smart-UPS 1250. Quite a nice piece of gear if I do say so myself, but they
ain't cheap. I think mine cost like $900 new. Another nice feature of the
UPS approach is that via a 9 pin serial connection and some software for
your computer, you get real-time displays of both input and output power
quality including:
Frequency in HZ down to 1/10 of a hz
Voltage in
Voltage out
Highest voltage input experienced
Lowest voltage input experienced
Same as above for output
Not to mention the fact that the P.C. can log to a file any and all
power events on the UPS, as well as just periodic logs
And, if you needed ABSOLUTLEY stable power for a short period of time,
you could deliberately run the UPS off battery for a while. My UPS can run
for up to 30-40 minutes with a small load, time decreases with increasing
load...... Totally switched and filtered power, and completely computer
regulated, to boot.
Worth the money, IMO.

my point was the viability of some sort of self monitoring power

you were the first to try it, you are! The first person in 10
years..........
I was looking forward to responding to you, to point out what a moron you
are, but after your last post, there isn't much left to point out. So,
carry on referring to yourself in the third person if it makes living with
yourself more tolerable. And since you are so increadibly fond of lower
anatomy, I hereby dub you "Lord Vulva"
l8r!
BTW, don't expect me to make this thread lamer than you and I already have.
If you are too silly to let this drop, then make it private e-mail.

Yeah, I'd agree..but doggone it, I used to have
some kind of Sola CV xfmr which I swear just had
some kind of capacitor(s) hanging off one side or the
other, not the relays. Had a cage on each side of the
xfmr.
The complaint I remember hearing about those kind of xfmrs
was that the output wasn't a clean sinewave.
Maybe someone who knows more about that type
of xfmr than I (maybe Steve Bench?) knows what the
details are on that gizmo.
But otherwise, you're right, they should've
regulated the PS anyway.
I used to have a big-ass 100 lb Lambda
with a mess o' 6L6's on the back that
with 500 ma, would've tested a whole
passel of tubes all at once..
NOt an expert, but I know something about these pigs. They are basically a
low ratio step-up tranny that is designed to saturate at outputs over
120Vrms. They hang some big caps for filtering and I think loading. They
tend to put out a flattened waveform at anything above the minimum rated
input voltage (usually 90v). The regulation is entirely within the tranny,
no switching or wipers needed. The excess V turns into losses in the iron
- it simply distorts clipping the excess.
This output may be a problem depending on the type of rectifier and filter
in the equipment used. Most fullwave rectifiers like the flattened
waveform, less filtering - but higher frequency noise. It's a bit late for
my brain to work properly, but some filtered supplies will put out well
over the intended DC voltage when fed from a Sola, and I don't recall which
ones. Note that the actual power under the voltage curve isn't regulated
only the peak to peak voltage.

I have one of those giant Lambda regulated tube supplies, and 100 lbs.
probably isn't much of an exaggeration. I just about injured myself hauling
it from the hamfest out to my car.
