Bought one of these used. One channel did not work. No power to 2 power transistors. Looked very simple to work on. Recapped everything. Found one cap did not match schematic. The polarity on the cap (Main Power Board) was incorrect. Also many errors on the board made by Scott. Terrible inaccurate job of manufacturing the board. I was measuring different places on power board with respect to ground when it sparked and smoked a 1/2 watt 330 ohm resistor. One power transistor and several others and a few diodes on the board were taken out also. the heat sinks were hot and shut down unit. cannot seem to locate the transistors yet. Pioneer was much easier to work on and paid attention to details. what turned out to be a neat little amp is more like a search nightmare with no parts that I can find.
