Who makes small (pc mount, signal-level) audio transformers these
days?
I need..
potted or decently varnished open-frame
3:1 stepup or so, maybe 60:600 ohms or such
50-100 mW
50 Hz-30 KHz, but maybe reduced voltage swing at low frequencies
0.6" cube or less maybe
Under $10 at 100 pieces
This will be used on the output of a multichannel wave/function
generator to boost the output from 20 v p-p (opamp levels) to 60 v p-p
floating. SSRs will kick in the transformer when it's needed, to
simulate VR speed pickups or engine-driven alternators in jet engine
test stands.
I looked at Triad and Tamura, and got some near misses. The catalogs
(Mouser, Digikey, Allied, Newark) have very little audio stuff these
days.
