I have a home theater system and also a tube stereo system. Both systems are sharing the same front left and right speakers, and I want to build a switch box to easily switch from one to another. Frankly, I am tired of manually doing this. T.H.E. . . B.O.X front: Rotary A/B switch back: Inputs:Tube preamp right channel RCA/coax Tube preamp left channel RCA/coax SS preamp right channel XLR SS preamp left channel XLR Phono right channel RCA/coax Phono left channel RCA/coax 120V Power 12V Power Outputs:SS amp output right XLR SS amp outputs left XLR Tube amp outputs right RCA/coax Tube amp outputs left RCA/coax Phono right RCA/coax Phono left RCA/coax SS 120V (5A) out 12V trigger to relay out Tube 120V (5A) out External power supply: 120V in 12V trigger in for relay SS 120V (5A) out Tube 120V (5A) out activity: SWITCH A position - Tubes Power off the SS preamp 120V using relay (the amp will be switched off using the 12v signal) Power on the tube pre and amps 120V using relay. Switch phono RCA outputs to tube Switch amp RCA outputs to tube SWITCH B position - SS (Home theater) Power off the tube pre and amps 120V using relay Power on the SS preamp 120V using relay. (the amp will be switched on using the 12v signal) Switch phono RCA outputs to SS Switch amp XLR outputs to SS I am having difficulty discerning what rotary A/B switch I can use to make all these things happen at once. It needs to be a 2 position (A/B) type switch, and switch the 120V relay, the phono section, the tube preamp-amp section, and the SS (XLR) preamp-amp section. Thanks, Craig
