i bought a Yamaha RX-V773 AV Receiver during the boxing day sale. i completely forgot about my current receiver having a switched AC outlet on the back, into which i had plugged the power amp for the subwoofer, as well as a 12v transformer and some fans to cool the cabinet. The new receiver has a 12v 'trigger' port on the back, but it only sources 15 mA! i found a solid state relay online which had the correct specifications, but i couldn't find a canadian supplier, and also could not find it on eBay. i went to Gervais, but they didn't have anything, but i found a solid state relay at Active Components. It was 5 to 32VDC in @22mA max, 24-240V out @ 10A max NTE-1010-51. i put it into one of those metal AC outlet boxes, which could act as a heat sink if necessary, and it works like a charm!
