Hi all, I am new to this forum. I've built several guitar amps from scratch using the information on the AX84 site, and now I want to build a tube stereo amp for my turntable. Last week I was given two organ amps and a bag full of tubes- one of the amps appears to be a stereo amp. I have been searching images to hopefully find a schematic for days now but I haven't found any images that match- do any of you recognize this one?

Welcome to the forum!
I'll move your post to a section where it will be better served. Since you want to build a stereo amp, it will go in the tubes/valves section.

The decent size of the power trafo and choke, along with what seems to be a 5U4GB rectifier indicate that 1 or more additional electronic modules were powered by that PSU.
If only 4 wires come out of the the O/P "iron", my hunch is confirmed. Full pentode mode SE 6BQ5s produce 5 WPC. Upwards of 95 dB. sensitive speakers are in order. Got a pair of Klipsch "Heresy" speakers?
A 12AX7 and 2X 6BQ5s are all that's needed. The "extra" 2 Noval sockets might be used for a phono preamp.
The OEM ceramic insulated RCA jacks will be serviceable after DeoxIT cleaning and the use of appropriate (Neutrik/Rean NYS-352G) plugs. FWIW, I do some sheet metal cutting and install this sort of RCA jack, to provide modernization without introducing mechanical weakening.
