I dropped my 1971 K-100 off with a local amp tech to see if we can eliminate the baseline hiss. Someone here mentioned that replacing some of the transistors with modern equivalents can go a long way to quiet the amp.

My tech identified the probable culprits: one 2N3638A and six FS35677s. Does anyone know what transistors to use for these?

I found an NTE equivalent for the 2N3638A - NTE 129. Is that the best / only option?

I can't find any info on the web for the FS35677. Is there a replacement for this?

Thanks,
Bob
