Schematic needed: Peavey Model 212 Classic

transformer, but a print would be nice. BTW, does anyone like
Hammond make a replacement for the power xfr?

A simple call to Peavey Support will get what you need.
..or, I believe, it's in the newest Darr Book.
....or..google..I'd bet it's out there somewhere..
I think it's a simple 4x 6l6 trans, and enough info on
the schematic to give ya details. I'll search for it
when I get home. I'd also guess PV will sell you a tranz
for less then Hammond (and I like Hammond Tranz)

coming very soon

Have you contacted Peavey directly? Things may be different now, but
they emailed and mailed a hard copy to me when I needed a schematic in
the past.

** Easy to find - once you get away from all the schem for the " 212
Classic Vintage " model.

** Nope.
The PV tranny has a main secondary of 365 volts at 350mA.
The bias / preamp winding is 54 volts at 150mA.
The filament winding is 6.3 CT at 4 amps.

Thanks guys. I forwarded the schematic to my brother who actually has
the amp, and he said the preamp section has ICs in it. I asked him if
there were any other markings on the amplifier. From his email :
"There are no other identifiers on the unit. The front panel reads
'Classic VT'. The rear apron reads 'Series 100'. It is a hybrid amp
with CMOS ICs in the preamp section, not discrete transistors. This
is important as the power supply needs to provide the correct +/- rail
voltages for the OP amps. It has a pair of 6L6s as finals. No other
tubes present."
I still haven't gotten a response from the email I sent to Peavey, so
any other information would be appreciated. Thanks again.

You could always use a seperate transformer for the bias/front end and
a general replacement (Hammond, ect) for the output section. Its may
be a bit of a "kludge", but we're not dealing with a desirable vintage
piece here.

** Tell your brother RC4558s are not "CMOS " ICs - but common,
bi-polar dual op-amps.
Made by TI and Fairchild among others.
Seems to be no schem on the web for that version of the PV Classic VT.

I'm all set on the schematic; Peavey emailed me a .pdf today. It's
the correct one with the ICs.

I called him tonight to yell at him (believe me, he KNOWS better), and
he told me he didn't look at the numbers on the ICs, but said that
there's
a label inside the cabinet that cautions about CMOS devices inside,
and to use the proper precautions when working on the amp. He did
mention
a Gibbs unit inside, so maybe the reverb unit uses CMOS devices. When
he gets the parts list, I'll post back. Thanks again
for the help.

You just replied to a post that's NINE YEARS OLD.
Trust me, there is no-one here who gives even half
of a dead rat's ass about your POS Peavey. This NG
was long ago highjacked by rabid leftists, atheists,
America-haters, progtards, socialists, communists,
perverts, no-blowers and the like.
So have a nice fuckin' day, mmmmkay?

Yes, that'll work (bias tapped from HV winding); nearly
all tube power trannies have filament windings. (Some have
two - 6.3 for the audio stuff, 5.0 for a rectifier tube.)
So two trannies would do it - you need the other one for
the low-voltage SS stuff. But what you want is the *right*
tranny - get with Mercury Magnetics. It looks like their
P-CL50-P might be the right one - you'll have to call and
ask. If that's not the right one, you can send the bad one
to Mercury and they'll rebuild it for you. It won't be cheap,
though. If it's a tranny they don't currently offer and they've
had requests for it in the past, they'll cut you some slack
on the replacement so they can clone it while they're rebuilding
yours. Tell 'em Lord Valve sent ya.

I recall getting the original transformer direct from Peavey. I don't recall what I paid for it and I don't know if it's still available. Send Peavey an email with any identifying numbers and see what they say.
I don't have the schematic on my computer; I believe it dissolved with my last hard drive failure. I'll see if my brother has it if you can't find it.

I bet you swallowed a good part of Phil that year as well.
And that WD40 was useful in lubing up your asshole.
