ive got a real problem. The power board for this AVT150H had been removed when I got it. And I can only find pictures of the board off the amp. It’s an unusual board for the 150H. It has two mosfet chips instead of one and many more resistors and caps. It mounts on a Heat Sync Block that also has two power connectors from the transformer and they are off set from the block via a round plastic set off. Only one screw hole in the Sync Block. In order for the Chips to touch the block the entire board has to go into the amp upside down. And that’s not easy. Can anyone show a picture of how this is mounted to the block? Sure can use the help. If you need to see a picture I can send you one.
