That looks like a zener diode nightmare!!!
Julius used the zeners in a daisy chain to do the alignment procedure on the early versions of that amp, the pair that Ted and I did we brought them up to date using a single zener and an adjustable resistor, much easier, that amp has chains of 10 zeners in a row...WOW That's Beautiful!!!
I'm sure George will suggest a complete rebuild, that will be pricey but money well spent. They are awesome sounding amps.
I'll check the stereo amp for model number when I return home, I'm using it in my bedroom driving a set of Von Schweikert model 4's it has no problem at all driving them.
The stereo amp will put out 60 watts per channel, the mono like yours will put out 90 to 95 watts with a strong set of matched tubes properly aligned.
