Default Golden Rules of Troubleshooting

Ah, they ain't no how as bad as all that these days. Between the various
mods, Factory and susequent, they have been rendered pretty bullet-proof,
very stable, and as simple SS amps go, fairly melifluous. They were made
in the uncounted tens of thousands, and uncounted thousands survive. With
a few hours of simple work and not much cost, a decent 50+ watt amp may be
had. As it happens, I keep two (full mods) that see very rough service, and
have done so in one case for 2 years of 24/7 use in a desert climate, not
conditioned. 100F+ from may to November. It now sits in my shop system
seeing about 3 hours per week, these days.


Who would put a curtain over an amp capable of frying an egg in the first
place?? That smacks of terminal idiocy.

Personally I wouldn't use an ST-120 simply because I find capacitor-coupled
amps to sound muddy, and yeah - I hated working on the things. Piece of crap
really.

Prefer direct-coupled amps (with a competent protection circuit!) although I
do like an autoformer coupled McIntosh...
