First, I have no financial stake in Electronic Goldmine, I'm just a satisfied customer.
I got that when you brought it up before.
I needed some transformers for a special project and Electronic Goldmine started offering these.

" Microtran Pico transformer type PM34-M is a miniature fully encapsulated 50mW rated 600 Ohm C.T. to 600 Ohm C.T. transformer. Frequency response is ±2db 300Hz to 100KHz. Has 6 full length leads. Size only 0.3" x 0.4" x 0.425" tall. New "
Not bad for communications gear, but for more general audio uses that lower end of the frequency response is pretty pitiful.
Electronic Goldmine offers surplus, new old stock, components and probably doesn't have oodles of these.
I did take a look at their site, lots of interesting junk there. But I really need to deal with the junk I have here first, I think...
60Hz appears be just over -3dB. YMWV depending on your system. Short pulses of 1 cycle or 1kHz show minimum ringing.
These could be ideal for coupling a computer to a ham/shortwave radio, PA, or other interface needs.
