I recently bought a zapfilter mk2 for my denon and I am having trouble with the power supply. I went online to look at the connection diagram and it was useless. The wire colors did not match the transformer I have.

So I was wondering if someone had recently installed a zapfilter mk2 and could either tell me how to wire the transformer for the US or tell me how to figure it out for myself. FYI, I have the power supply with only the secondary connections on the board.

Well, I figured out the problem. The diagram on the lc audio page was wrong. The purple and black + red and yellow should be twisted together for 115V operation. As far as the zapfilter, the sound is much cleaner and balanced, a nice improvement.
