In Reply to: RE: You will need a separate PSU, as well. posted by tesla on February 17, 2016 at 15:01:07
It's not a 22 anymore, just looks like one.All the valves are 12A_7s. Viz. two 12AX7s for passive RIAA trimmed to < +/-1 db, feeding a 12AT7 also used for line-source gain, and a 12AU7 in CF for line-drive down 20 plus feet of IC. It can swing up to 40 volts. ALPS volume pot, no tone controls.
All currents are regulated, HT and DC 12.6V filaments, and is big enough to run a 15wpc PP power amp, so he tells me.
I will ask him, but he may not have documented it.

Mr. Wright is, sadly, deceased. ;> ( Melanoma, IIRC.
IMO, the logical contact is Joe Rasmussen.

Thanks
Proudly serving content-free posts since 1984.
Yes, AW moved to Germany a good while back, and I knew he was dead.
I haven't dealt with Joe Rassmussen since the mid 1990s?, but neither point matters.
Because it isn't an AWE FVP anymore.
The separate PSU - hardwired - is not the original one AW built. And it's now in Mk III form - rebuilds by Bill Crampton - most recent being late last year.
I will contact Bill as soon as I am fully recovered from my hernia surgery, and because I need to anyway.
Heaving the four bass duty spheres around, as part of the new main system plans will need to wait until then.
LBNL I don't recall if EF86s (4 of in a QUAD 22) run on 6.3V OR 12.6V only or either. So, the PSU may not be of use 'cos it's 12.6 only.

Greetings from up over! I feel your pain, friend. You are used to being active, popping a stitch is not conducive to activity. Hopefully you'll heal well. Just be careful lifting those tube amps! I don't have enough use of my left hand to lift my Citation II. Lucky for it I won't butcher it! Be well, Timbo,
Jim
EF86 is a 6.3 VAC only type.
