Doug, in one of my Zenith HI-FI manuals, it speaks on how to convert the germanium transistors to the silicon ones on that amp--some tech wrote it in there.
From what I remember--it involves changing, and in some cases, shorting over, some resistors in the output/driver ckt, and replacing them with MUCH lower values, and putting in sils. for the transistors, probably ECG-219 or so.
But, I have to ask...just WHAT is wrong with germanuim transistors anyway?? I have a couple of the Zenith stereos and several amp, or one-piece chassis with germaniums. In the big sets like ours--those amps sound VERY nice and powerful with those gers. in them? Why change them--if they are ok??
