I'm here in Dallas with a ST70 I bought 10 years ago.
I knew it was in very poor shape, ( as in wires all cut up )
but because of money, job stress, etc.. I am just now
getting to assemble it. ( After seeing the VTA board )
I would appreciate some help in deciding what to replace,
which options to choose on a VTA basic board, and also
have some backup when I have a question about assembly.
I'm so glad I didn't buy other upgrade kits ( like Van Alstine )
or such, and feel pretty good about buying a VTA board with
whatever else I need.
This amp basically only has the original tube sockets, power transformer,
audio transformers ( the board is original but I don't trust it at all,
seems some people think putting 100 wonder caps will make an amp 100
times better ) and some hardware. There is some rusty pitting on the frame
but the cage looks pretty good. I don't really mind it is not in perfect
cosmetic shape, I just want good reliable sound.
I have another ST70 in original shape ( yes still has the selenium diode that
I know I HAVE to change ) so I do have a physical model to compare to.
If only someone could enlighten me as to the electronic schematic
and functioning of a 3 inch solid copper wire, I could just maybe
get this done.
I'm going to continue on the next post to separate
my ramblings with my proposed purchases and questions about
assembling the new amp.
