Also, I haven't counted recently but what if I have lost a couple of the thermal pads that are sandwiched between the FET's and the heatsinks? Can I just use thermal paste? I have a tube of Arctic Silver Ceramic from a PC I built a few years ago. My concern would be consistency in thickness. Are those pads easily found? I see that digi carries thermal pads but I don't have a micrometer to measure them to be able to order the right thickness and size...

No you cant, you must have the anodized aluminum pads, or you can use a kapton tape as long as the heat sink is smooth and nothing will protrude through the tape and touch the fets.
If you just use paste the fets, regulators, and rectifiers will short to the heatsink and the amp will go "POOF"!!!

Order THIS and cut to size or use mica insulators (D-K #4671).
I'd suggest using standard heatsink compound.

So I lost ONE! One stupid pad! sean I'll send you a PM with my email address. Are they RF originals? I'd only want 2 of them so they could most likely be sent thru a letter envelope. How does $1 "shipped' work for a pair? Check your inbox. Thanks!!!
Anyone want to help me repair my wife's elliptical machine? I plugged it in using a too high voltage power supply and fried some components on the board. A new replacement board is $200 and we only paid $350 for the whole thing! If not here, where can I post for help? I've found two obviously burnt components, one of which is a resistor. |
