Description
Headphone Adaptor for Power Amplifiers
Add a headphone socket to any existing stereo amplifier that doesn't have one. This L-pad attenuator hangs directly off the power amplifier(s), and you can choose to use the DPDT switch inside the socket or not. I would suggest for power amplifiers above 20W RMS NOT to use the switch. I don't think the contacts could handle the current.
