    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.

    You should post pictures.
    There should be thermal grease between the IC and the heatsink.

    Yes I have that grease I just can’t get the bracket that holds the AVT100X-62-00 board in place. There are several problems in mounting it so the chips are on the heat sync.

    If I could get a picture of the 150H with the AVT100X-62-00 board mounted inside that would help a ton.

    Click "upload a file," or click "more options."
    Click on the file you want to upload.
    Files should be changed to GIF or PNG using microsoft paint, because there is a limit to the size of the file you can upload.
