Has anyone built one of these? If so, are they a good first project?

I have not built one. It looks about like building a Champ. That is
one clean schematic. I would think it's a fine first project.

Thanks, Les. I've been looking through their 'theory' doc and it
appears to have enough to answer any questions about some of the amp's
whys and wherefores without swamping a person. Might come out of this
a bit more knowledgable than a strict 'Champ' build because this has a
full FMV tone stack as opposed to none.

The kit price seems reasonable for my needs and it would fill a void
in my sound pallette right now. Since getting rid of my Lonestar
Special for the Mark 5:Twenty-five, I no longer have the single-ended
EL84 class 'A' mode to work with. I'm hoping something like this
would fix that jones for me.

For a yutz like you who can't tell a phase inverter from a
fire hydrant, thinks certain diodes are magical, and doesn't
know which end of the soldering iron to hold (and can't tell
a B-flat from a beer can) - offhand I'd say you'd be better off
with a Pod. Worship my diodes, baby! Dig my Clapton patch!

optimistic. And don't expect me to provide links to any

Yeah. It's good documentation.

Yep. Still, it doesn't get any simpler.

I expect it would. I am tempted myself - that's a good price for a kit.

What would be even cooler would be if there was a way to swap a 6V6 for
the EL84 at will with minimum fuss, for more of a Champ vibe.

I don't know if this fits your bill but in their option plan there is
a mod to allow you to run an EL84 and a parallel octal tube. Another
mod takes it down to 1W by changing it so you run a 6N1P in place of
the EL84. They do two more advanced P1 kits and also do a
single-ended kit that takes any one of KT88, KT77, KT66, EL34, 6L6, or
6V6.

Try one of their forums. Someone there may have tried what you are
wanting or have an idea how to accomplish it.

Moving forward, I have a couple of questions about tacking components
and wire to the eyelet board. The caps provided with this board have
radial leads so it will be a case of laying them down against the
eyelet board and bending the leads. The documentation suggests using
a clear non-hardening silicone to tack the caps to the board to
prevent them being shook around. Is there a silicone that doesn't
offgas corrosive materials that can be used safely for this purpose? I
was thinking of using hot glue at a lower temp but then thought of
potential difficulty removing the cap later if needed.

Another item I was considering is tacking the small amount of wire
that runs under the eyelete board in place as well. It appears from
the layout diagram to be run deliberately to avoid paralleling
component leads but cross under them at right angles. My thinking was
that a little encouragement staying in place wouldn't hurt. I'm using
stranded wire this build and don't expect it to be quite as
cooperative staying put.

Thanks for the replies.

Not very challenging. Go with a 18w TMB.
.

[Rick N. Backer]

For a first build it's challenging enough. Taking slow steps so I
hopefully minimize the troubleshooting phase first time I throw the
switch. Thoughts after this are to build an SE with a pair of
parallel 6550s. Just because. <G> I may actually attempt a true
point-to-point build.

Anyway, it's moot at this point. The kit is here. I've had the
chassis powder coated white, ground the coating away for the two
ground lugs to have purchase and am about 1/2 way through the circuit
card at this point. Hardware is already mounted on the chassis just
waiting.

In the meantime, while I'm waiting for hookup wire to come from Mouser, I thought I'd build the Electra distortion pedal to put in front of it when it's complete. The distortion pedal is an easy build. I'm going to do the next iteration of it with selectaable diode combinations. The Electra was originally an onboard for a guitar that was made in Italy. Premier Guitar has the article with BOM and instructions.

I'd also like to attempt this project, but am looking for a kit that
has a cleaner tone. Too many (all?) of AX84's amps say, "cleanish".
I'd prefer "clean".

When I get this done I'll give you an eval. If I'm up to it I'll see
if I can't make up a demo. Clean is in the eyes of the beholder as we

this will put out if you're trying to keep it clean at any volume.

Nah. I'm jes an old geezer floggin' frets at home. Don'e need much
in the way of amplification. I guess I can settle for a not-so-clean
tube amp, as my Mustang I cleans up pretty nice when I plug in my Tele
and by-pass the pre-sets. I jes wanna learn the theory of
tubes and make my own amp.

The AX84 site has some nice theory info. Despite my wandering off
into mechanical engineering, I am still fascinated by electronics and
now that I'm retired and can diddle around, I wanna try some real
electron hacking. Plus, I got all the basic tools and building an amp
looks like big fun. ;)

[Rick N. Backer]

The only thing I wasn't up to was the chassis construction. I have
since acquired a drill press. Although punches would be neater,
they're cost prohibitive for one-offs. And that's just standard
holes. You start getting into D holes or some of the trapezoids you
might need they're $300+ a punch.

That said, the chassis with the Doberman kit works but is not really
friendly for cabinet installation as there are no flanges for mounting
hardware. I have a gentleman building me a couple of speaker cabinets
and we are going to see how creative and artistic we can be with some
sort of housing for this head.

A good start, but you might try a sheetmetal nibbler. Harbor Freight
sells an electric nibbler for under $50.

Don't forget to post your build pix. ROFLMBFAO!
And mind those DIODES!

[richardni...@gmail.com]

They do provide a chassis when he has them. It is fairly skookum, .090 aluminum. It is pre-punched for the P1 or the HO or Extreme upgrades. Leaves some spare holes. I've used some of them to screw my cable tie anchors to. I figure the extra socket holes can function as heating vents for the underside of the chassis for now.

bleat about diversity (which none of them practice)

all the destruction of America (which many of them
are actively working to effect) is a fascinating

I'll push their buttons and watch them screech. And
we'll never see any build pics from any of them.

I could clue 'em in on how to keep it clean, but doing

Chassis is all laid out for the circuit card to go in. Tested voltage on the heaters and got 6.9 at the heater pins on the socket with both tubes installed. 7.0 at the pilot light. Are these within reason? Will they drop some as the transformer is called upon to do other duties with the rest of the circuit in place, i.e. providing the B+

Circuit card is all wired and sitting on the standoffs. Think I'll spend the weekend soldering the individual stages in and running some tests. Still need to put the current limiter together before I fire this puppy up for the first time.

One thing I would not do next time is have the chassis powder coated in its entirety. The inside is a nice gloss white but I had to grind some away so the grounding lugs would make contact. I'll mask the inside off if I powdercoat next time. Might also go for a brushed aluminum finish with a clear coat.

Picked up a surplus Fluke 8030A as I wasn't certained the cheap chinese hand-helds were giving me RMS readings. The Fluke does. Re-tested the heater feed and it was 7.36 at pilot and both tubes' heater filaments, tubes in. High voltage shows 220 on each leg, unloaded.

Ran my voltage checks today on the P1 and am happy with results. All
voltages are within range. Plate voltage on the 6P14P is 253 with a
cathode voltage of 6.2, cathode resistor is 130R, which should give me
a bias point of 48mA. Spec on the 6P14P says 48 +-8 mA so I'm feeling
very comfortable. Tomorrow will be guitar day and I am told to get

Plugged a guitar into it today and ran the amp out into a 180W 2 x 12
cab. It wan'ts going to work the speakers but gave me a chance to
listen for noise. Shielded wire on the signal chain is doing it's job

for sure. There's some thermionic background noise as you bring the
gain and volume up but it's minimal. Voice wise, it's a little harsh
when driven but it hasn't had a burn in yet so I think I'll do that.

After that, if it's still edgier than I like I'll probably pull the JJ
12AX7 for something with a lower gain, maybe 70 or a tad lower. It
has the Russian military 6P14P in the power section right now. I'll
give it a fair listen but I also have some other EL84s I'd like to
check out in it. I'll probably run it through the 30W Weber in my
Victoria 5112 so it's got a speaker closer to what I'll finally match
it up with.

It will be fun for a while. Once I'm happy it's as quiet and hiccup
free I'm going to look at some of the documented mods. Probably in
this order; switchable output, move it from self-bias to fixed-bias,
and add a parallel octal power tube.

Shot noise is not "thermionic" noise, you blithering fuckstick.
Semiconductors also exhibit shot noise.

Probably just Johnson and shot noise from resistors. Is the noise a hiss
or more like impulses?

I presume you used carbon comp and not wirewound or film resistors.

Single ended amps are harsh.

If the Weber has more rolloff it will probably
be less harsh than the (presumably higher-compliance ) 180W 2X12.

I have an amp with a presumably ( it is unbadged ) Eminence EPS15C now.

It's on a line from the classic JBL K1x0 D1x0 and Peavey 1501
speakers.

It is very very good at taming harsh. 30dB drop @ 2k over
a few octaves. The whole amp (Quilter Steelaire)
is designed for sculpting the upper mids.

That's exactly what I'm dealing with, Les. It's at a very low level
though so I won't be spending an inordinate amount of time with it.
I'm actually quite happy with this build for a first attempt.

No carbon comps anywhere in it, all metal film or metal oxide.

I've got a couple of different 5751s and either a 12AT7 or 12AY7 I can
try in the pre-amp stage, maybe a different branded 12AX7.

Sounds good, Les. Sounds like you really like it. I'm looking forward
to tweaking this little project and then attempt something a little
bigger. I'm thinking an 18W EL84 based amp along the style of the
Marshall that had that configuration or try a multi-tube paralled SE
build. It might be interesting to build a 4 tuber that I could just
drop power output by pulling out the necessary number of tubes. :)

Huh. You should get minimal hiss from film resistors.

Just checking - you did check it with the input shorted, right? If you
know the gain from the input to the speaker, roll all the knobs to
1) all up for gain knobs, or 2) zero for EQ , then that gives you a
estimate of how much noise it is worst case.

Think speaker... this'll need something lower compliance, I will wager
- although running it all out into a floppy speaker might sound cool .

Be nice to know how it does with a quad of V30s. I bet it's cool into that.

I'm really impressed with that speaker.

Could be - most parallel SE amps I have heard were pretty nonlinear.
You'll be swapping tubes forever. :)

I'll run through it again. A couple of times. I pretty much just
used the startup steps from Paul Ruby's site. I can't remember how he
said to set controls but, memory serving me correctly, it was as you
described. Preliminary assessment says it's in the gain stage at this
point. I will probably go over the Gerald Weber DVD I've got again
and pay some attention to his troubleshooting advice, just not the
two-fisted voltage probing. I also have a trio of more trained ears
coming by that should be able to identify what we're hearing and if
anything is amiss.

Ran it into the Weber today and it is a lot nicer sounding, a little
less sterile. I swapped in a JJ EL84 for the Russian 6P14P and I
think I prefer the JJ at this early stage. In fairness though, I took
some Deoxit to the 50 or 60 odd year old pins on the Russian and have
it back in. It did clean up some of the noise related to bad contact
so I'll give it another go. I have three different EL84s on the way
from Tube Depot as we speak. Will give them all a chance and see if I
can't find a best of breed amongst the four I'll have available.

[Les Cargill]

Probably.

After doing a tube roll in the pre-amp section I've eliminated the
noise. Turns out the JJ was just a noisy tube. I tried an old
Sylvania 12AU7, an old Matsushita 12AX7 (both pulls that were donated)
along with a new E-H 12AX7. The noise was gone in all cases. The P1
seems to like all the alternates I gave it so it will be a matter of
playing with it a bit until one of them speaks to me more than the
others.

[Rick N. Backer]

Correction, E-H was a 12AY7

That worked out then. If it hadn't been the tube, it would have been
a bit of a knucklebuster.

It's unusual for a tube to go just hissy without any impulse
noise.

I like the A/H 12AX7s for a first gain stage.

Finally got around to adding the output selector switch so I can run
4/8/16 out. Just had it set up for 8 initially.

The only switch I could find seemed a little on the big side. Had to
bend two lugs over so I didn't have anything extending below the
chassis. The switch was an NKK HS13Y. If anyone knows a better
switch to work with it would be appreciated.

Next step is to move the amp from self-bias to fixed-bias.
