First, I have no financial stake in Electronic Goldmine, I'm just a satisfied customer.

Electronic Goldmine offers surplus, new old stock, components and probably doesn't have oodles of these.

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.
