Lol. Always a smartie pants I am.... smile

I knew you knew. Just making Vic aware of what can happen if he jury rigs stuff.

BTW thinking on this the 230v switch on the amp is likely for users overseas. It is not North American 240 with 2 hot legs. In the UK etc they have single leg hots at 230 instead of 120. Likely still set up for one pin as neutral with the torroid tap.

Just stick with 120....

Also, I can back Mojo and rrlev that a single 20A cct is fine. I run a 2200va centralised UPS in my mech room that serves the basement HT, living room plasma and oppo and a 2ch room setup. Runs all three no issues simultaneously.

Had a BBQ party once and the power went out. Ran the 2ch setupfor 45 mins on battery cranked and kept BBQing.... power came back. All good. Pretty sweet with 15 people here. Lol.
