Well, it's buttoned back up and is now in service next to my workbench, where it has (temporarily) taken the place of my Fisher 432. So far, so good. It is behaving itself and has shown no further inclinations of releasing the magic smoke.
The only issue I notice now? The right channel is louder than the left. Not by a huge amount, but noticeable if the front balance control is set to the very center. Moving it somewhat to the left balances the channels.
The left channel audio amp board still has all of its original transistors, only the electrolytics have been replaced and three of the film caps. On the other hand, the right channel audio amp board has all new transistors, all new resistors, and all new film and electrolytic caps. Only the diodes, trimpots, and ceramic caps on the right channel board are original.
It looks very impressive and sounds very good overall.
I'll try to post a photo later.
