Even Peavey did not have any info on this amp, and I could not find a similar Peavey power amp design anywhere. Before this amp, I thought all Deuces had tube power amps (and phase shifters!).
The power amp in this amplifier had suffered catastrophic damage, and instead of trying to repair it with no information, I just installed a couple 100W "HiFi" power amps in place of the existing PA. We also completely recapped/overhauled the amp.
