I have a few pictures that I cannot post until a week from now.
The ST-70 never sounded perfect, it sounded good, but there was always a hum or a hiss or a crackle. It wasn't taken care of and I have it now.
The amp turns on, the tubes warm up and glow their normal glow, but I have no audio output. I've tried different sources. It does not make a "thump" sound like mentioned in the manual (It used to). So far, all the tubes other than the 7199's have been replaced (I had a rectifier go a few months ago). A new capacitor was just installed today under the advisement of the person that gifted me the amp. I'm probably sure he's a member of this forum.
I'm not sure how much it would cost to do a rebuild, but I have some amazing Klipsch loudspeakers to use with this thing, and I'd love to get some information on what I can do to get this going under a constrained budget.
