    Sorry - I kind of lost track of this thread for a while.

    Here again I don't have specific experience with a 400RB, but on the 1001RB I did I had to remove a crapload of screws to get the heatsink off. Specifically every semiconductor mounting screw. Also in the case of that amp the PTC resistor was located under the heatsink and I couldn't even identify it until I got the sink off. Are you sure you lifted the PTC? maybe that amp layout is different...

    You really should see about getting a schematic from G-K. They were real friendly and shot me a PDF of the 1001RB schematic right away when I called. I'm not G-K factory-authorized or anything either. Nice company.
