Phase Linear 700
Matthew Kirkcaldie
I've acquired a Phase Linear 700 power amp - in unknown state except for:
a. cosmetically good, and no sign of excessive heat on the heatsink
stickers, no corrosion on internals, etc
b. powers up, VU meters illuminate, etc
c. if I have it switched to the direct coupling inputs, the output power
indicator for the right channel shows power going out if I turn up the
control beneath it, hence I assume there is noise of some kind in that
input. It doesn't do it if I switch to the other inputs.
Of course I'm not keen to plug in my own speakers until I check it out
thoroughly.
Anyone had any experience with these? Online searches suggest it's Bob
Carver's first amp, and that some people love them and others loathe
them, for sonic and reliability reasons.
By the way, it appears to be a proper Aus model, with a 250VAC
transformer on the back with a Phase Linear, Made in USA sticker on it.
Weighs nearly 30kg!
Cheers,
MK.

Yes, I got that impression! Are they prone to sudden failure if they're
working well, or do you need to overheat them or give them a stupid load
to achieve the "Flame Linear" effect?

The original bad reputation was generally the result of transit damage due
to use in PA systems constantly on the road and misconnection of load or
inputs by half asleep / stoned roadies.
Even if you do nothing else, you ought to have a relay loudspeaker protector
fitted and use the smallest amperage DC rail fuses possible.

**Indeed. A risky amp to connect to expensive speakers, since the only
protection are two rail fuses. Most Phase Linears had major problems with
instability, but this was addressed in a factory modification. I suggest you
have it carefully checked by someone who knows them well and can ensure you
that the mod has been fitted. And PA's suggestion of using a speaker
protection relay is an excellent one.

he hasn't taken his meds for his bi-polar condition.
All my experience with Phlame Linears isn't positive.
In fact the guy brought me TWO rather very well fucked up amps;
both had died horribly, repaired many times before, different types of bjt
power devices.
There is a time to retire such crap.
I wish PA all the best in his promotion of these horrid dinosaurs
of the transistor era, I know his adoring crowd of groupies
will all cheer when he supports such dreadful amps.
But i won't be one of them.
I could add that the TO3 sockets can be unreliable, as I found in another
amp for a Leslie speaker for a Hammond organ.
And the heat sensors on just about all SS amps are like tits on a bull,
useless,
since the bjts heat up and die well before the heat sensor turns off the
amp in a short circuit situation.
My shed groans under the weight of SS amps that have died from shorts,
or just because they wanted to die, right out of the blue.

Patrick Turner
I see you are nicely wound right up Phil.
I can't/won't answer point to point, your posts are too full of demonic spew.
So I'll just say a bit more about why and how amps fail.
Why are so many dead SS amps weighing down my workbenches,
awaiting repairs?
Because short circuits DID NOT cause the fuses to blow.
The output transistors blew instead, plus emitter resistors, plus driver
transistors,
maybe the PS diode bridge, and other sundry bits.
But you go right ahead and keep thinking BS about what happens in SS
when they fuck up. I am not here to get you to agree.
Very often, the owners of these blown amps have had shorted speaker leads.
They turn on, walk away, but don't notice one channel is a bit quiet, maybe
distorted,
and the the amp labours away with an average 2+ amps at low volume into a short.
But hey, there is say +/-60v on the rails, so you got 240 watts of dissipation.
So the transistors heat right up and poof, they take out all this shite, and
finally a fuse might blow.
I have seen professional amps crap out, none are immune from the SS wobblies.
All fitted with "protection" .
Why did they need my attention?
The transistors blew anyway
Around christmas time I get quite a few blown amps from end of school parties
where
the under 18 get to se how loud dad's old system will go.
So the crossover heats up and slowly imoleates, maybe a bass seizes a voice
coil,
its impedance changes for the worse, then in sympathy a channel in the amp
fuses to a shorted mess and then a fuse blows.
What they do not fit to any amp I know of is a circuit
which shuts the amp down within 2 seconds, regardless of levels, when less than
3 ohms is present,
at any frequency. But they won't fit such protection because the companies who
make amps
WANT you to bust your gear so you'll come back for more, SOON.
The place the speaker terminals nice and close together to make sure
ppl will have frayed strands of speaker wire which will touch each other.
But then of course ppl make speakers of 4 ohms which go down to 3 ohms, maybe 2
ohms....
Polyswitches are not that wonderful, I have seen exploded remains in speakers,
amps.....

Putting aside for now the technical details of why these things
explode, I feel compelled to put in my ounce of subjective comment.
I've listened to two incarnations of the Phase Linnears (dim memory
suggests they were later models (700 Mk2 & the 500? ) on full range
ribbons a la Acoustat, Plannar hybrids from Magnaplanner , Tannoy
'Westminsters', Whatmough 'Ondines' Pro-ac 'Tablets' risky that last
one) and on all of these the Phase Linnears , TO MY EARS, sounded
utterly sterile and un-musical.
Maybe that's why so many audiophools actually like these monsters? Me,
I wouldn't go near one even if it was proven safe and came with
complimentary fire insurance.

** The 400Mk2 , 700 Mk2 and Dual 500 were produced **after** Bob Carver
had departed from the Phase Linear company that he originally started. These
amps were from another designer and bear only cosmetic resemblance to the
famous 700B and 400 models.
For example, the non Carver Phase Linears used op-amp ICs for the input
stages and employed hair trigger SOA limiting that made them useless with
other than 8 ohm nominal loads. The use of Aluminium package power
transistors and silicone rubber insulators ( thermal as well as electrical
!! ) proved to be disastrous for reliability in pro audio applications.
The models were soon abandoned and amp manufacture ceased by the early
1980s.

Speakers of 2 ohms are fine, as long as an amp is designed to drive 2
ohms
for extended periods.
For those not so sure, perhaps they could get 2:1 step down tranny,
so if the load is 2 ohms, the amp ses 8 ohms.
Setable protection circuits to allow say 2.5 ohms when set to match 8
ohms
nominal or for 1.5 ohms for 4 ohms nominal would be nice.
I replaced the entire circuit of the Phaze Funnier with a design of my
own with
10 flatpack modern bjts in each channel, to give about 75 amp ability,
and I added folded sections of al sheet between existing to double the
heatsink
area.
It didn't get hot after long tests, and sounded well.

**The ME protection systemS operate on several, quite different levels.
1) There is the most fundamental protection system. The fuse. This is
basically designed to prevent fires and massive over-heating, just like most
amplifiers.
2) The transformer, like all transformers designed for Australia, has a
thermal fuse, which is designed to open if the transformer reaches an
unacceptably high temperature.
3) There is a comprehensive protection system which senses several abnormal
operating parameters. If any of the following conditions occur, mains power
is shut down:
* Excessively high output stage temperatures (around 90oC).
* Excessively high levels of DC at the speaker terminals (around 2 VDC)
* Excessively high levels of infra-bass (This parameter varies according to
frequency. About 20 Volts RMS @ 25Hz, down to around 4 VRMS at 2Hz)
* Excessive mains leakage at the input terminals.
* Excessively high levels of high frequency information.
4) Output transistor SOA protection (AKA 'Current Limiting').
Although the protection systems in all ME amplifiers are far more
comprehensive than most, it is probably #4 that you are referring to. Almost
all BJT amplifiers use current limit systems, whilst MOSFETs achieve the
same thing internally. Where the ME system differs from most others is the
'gentleness' of how it is accomplished. Most SS amplifiers act ruthlessly on
the signal, when it exceeds a specific current level. This invariably causes
quite nasty distortion products. This is a function of three distinct
factors:
* A relatively early cut-in point of current limiting. (Typically 20 Amps or
much less)
* The use of high levels of Global NFB.
* The use of 'Brutal current limiting'.
ME amplifiers:
* Use a VERY late cut-in of current limiting. (Typically 40 Amps or more)
* No Global NFB.
* Gentle current limiting, where the waveform is reduced in amplitude,
rather than cut-off.
In the scheme of current (and Voltage) limiting, the effects of Zero Global
NFB cannot be over-stated. It is a crucial aspect of the design. What this
all means is that even the humble ME240 can be connected to the most
ridiculous loads, without fear that severe distortion problems will be
encountered.

heat up
inside their cases faster than heat sensing devices begin to work.
For more effective heat sensing, a detecting device should be
bolted hard against each and every output transistor case, not on a
heatsink inches away.
Many consumer grade amps just blow up because of the tendencies I have
described in earlier posts,
and because nothing detects a low load value. Two more silent amps
arrived in the last two days,
a Marantz, and a Pioneer.
It should be easy to fit a little microprocessor to

answer is below 2.5 ohms,

** Load impedance is simply not the issue, many famous speakers have
impedances below 2.5 ohms at some part of the range from DC to 20 kHz .
Output device dissipation and resulting chip temperature is the issue and
this is usually addressed by VI limiting circuits and or rail fuses.

Load impedance ****IS**** the issue with amps that fail.
Some amps might tolerate 2.5 ohms, but not all.

These DO NOT work when the speaker leads have shorted and the
gain control is set at a low level. The current can be below that required to
blow a fuse or
cause current /voltage limiting, but the Pa in the devices
still equals average V x average current, and the devices overheat radidly
and fuse to a solid short.
After that the owner brings the amp to tech for a fix.

Control over himself to enable himself to be socially acceptable is what

Only he can provide that for himself with counselling therapy and perhaps a

Hitler had a pretty bad temper . So did Stalin. Angry leaders of

celibate, ultimate say in worldly affairs, has the ear of

Sorry Ayn but you are probably the wrong species, not to
mention gender.

I read an article about temporary cases
of psychosis, according to the article by an
epidemiologist. These cases where the patient
eventually recovers can be plotted on a map
and just like an outbreak of disease there is
a central outbreak and then concentric rings
on the map formed by subsequent cases.
His theory is that it's caused by a
flu-like virus and is contagious. But this is
not Phil's problem unless he is a carrier.

around this little electronic coven, of variable gender. That would
make me the wrong gender SOME of the time.
Now that I think of it that could be interesting. (but not with PA,
unless I had control of the Harmon Kardon 'Soundsticks' 100% of the
time)

There was a guy in Melbourne. Name was Ian Rumbold (I think). He worked
for Ron Blackmore at Artist Concert Tours, and was a whizz at the Phase
700's, as they used heaps of them for their touring rigs. Don't know where
he is now tho'.
