I have a B&K CS-117 preamp which has a defunct power transformer. The
B&K folks won't sell parts and the cost of the parts, shipping and
labor will be more than the worth of the unit. I'd like to keep it in
service but the transformer is unmarked as to manufacturer and the
manufacturer of the unit won't give me the specs. I guess that I see
their point, in some ways, but at least they'd profit from selling me
a transformer and I could speak well of them. Is there a way to
estimate the output needed (it looks like a center-tapped output from
the 3 wires that go to the circuit board)?
What's the voltage rating of the main input filter cap?
