Bergquist thermal pads

Does or anyone have experience with the Bergquist products ? If building a F4 or F5 amplifier what would be best to use for thermal pads ?

Keratherm Red 86/83 (w fiberglass). If you ask the distributor they might send you a free sample.

Call me weird, but I like the aluminum oxide pads (available form Mouser). They conduct heat very well, and provide extra galvanic isolation, comforting for high voltage projects like the "SiC Puppy" and "Das Ist Aber Schade" amps. The pads are thick enough and strong enough that I haven't had any cracking issues as of yet. Conical/wavy washers would help a lot with that issue.

Folks:

I'm new at this and am in the early planning stages for two F5T V3 builds. Is there a meaningful advantage to the Keratherm Red 86/83 pads over other options, such as the aluminum oxide pads that wrenchone favors? I see that Mouser also offers Thermalfilm and Thermalsil III "thermally conductive insulators" (Mouser Electronics - Catalog Viewer). I'd like to get the best solution for my buck -- any advice?

Thank you,
Scott
