Re: [Drakelist] Female RCA on AC-4 Power Supply

Bill -

The RCA pigtail out of the AC-4 connector is for the speaker when the power supply is used with the TR-4, which has no other speaker output. Be careful though, as I have seen more than a few that have been changed from the Speaker pin (12) to the Linear Relay pin(s) (5 or 8) to get around the two pin connector on the power supply.

Can someone please tell me what the Female RCA short cable that comes out of the AC-4 power supply is for? The schematic says speaker but I have a speaker cable from my MS-4 that goes to my R-4C so I am confused. TIA for the help! 73
