Thanks for the offer. I have all the stuff laying around already. If you're like the farmers around here the main crop has been dust this year. Good luck with your yield.

Yes it is a AA920. The tube complement is 2 12ax7, 1 12au7, 1 5y3gt, 1 6c4, and 2 6L6gb. Right next to the capacitor cans is a potentiometer. All of the writing is gone. Is that a bias voltage adjuster? The imprint on the back says 110w. I assume that's consumption. Interesting of the input selector there are tape amp/aux/radio/tape head?/nartb?/RIAA/AES?/LP. Have any ideas on the ?

I think thats a mono amp. The RIAA is the eq curve for various types of record eq schemes. 78's used 27k I believe while most mono 33's used 47k to load the cartridge. Aux is line level as is Tape out. Tape head is a pre-amp for old tape machines. Check to see if that unit is a mono unit. If so start looking for the other channel on E-Bay. That is a keeper of a system. Look at the size of those transformers.
