Bridge an stereo amplifier to MONO

Mikewong · 27th July 2011, 07:18 AM

Amplifier like Adcom GFA-555 has a bridged-switch to switch the amplifer from stereo to MONO.
How am I going to bridge the amplifier without a bridged-switch?
Please help.

Here is a single line diagram. Volume and tone controls must be set to the same positions, Balance centered. The inverter could run of a 9V battery. Good luck! E
