I recently purchased a bunch of these and would like to make some mic
pre's and line amps out of them. What would I need, what were the
original transformers used? Company only sent a data sheet, said
nothing else was available. I found the pin-outs in the archives and
power requirements. But am looking for info regarding mods and what I
exactly need to get them running. I figure a input and output
transformer and a pot. But was wondering about real world experience
with these. I have read great things and would like some direction. Any
schematics out there?
