Clean Dynaco ST-120 Amp and PAT4 Preamp.
Forgot I bought these years ago and found them in my back room collecting dust. Thought about gutting them and putting in some class D Modules, but after connecting up on my variac and having no issues, and listening to them, I cannot help but want to just leave alone - sound great with slightest hum on my somewhat efficient speakers.
I never did any mods to them - looks like previous owner had power supply caps replaced...amp has slight rust pitting while preamp looks to be very clean. All preamp functions work fine.
Anyway, hows $275 + Ship (or pick up in West sub of Chicago) for both?

BTW - On the ST-120, I realized the B+ was 94vdc which was due to the Q9 PS transistor being shorted - replaced the 2N4347, now its a nice steady 72vdc...all ready for another 40 years!
