keratherm for mosfets on f6

[acowans]

Quick question, the keratherm has the woven "bronze; looking material and a separate white material - do I use both under the mosfet and if so is the bronze size down on the heat sink and the white material on top of it (under the mosfet) or is the white material just some some sort of backing material that's used during production and I don't use it at all?

thanks

Further to ZenMods reply. This is from the DIYAudio Store Keratherm product page for reference.

Hmm, this explains a lot about why my first attempt at an M2 burned up.

I use ceramic now.

Thanks ! Not intuitive and I hadn't seen the instructions for it either. Hmmm...I wonder which I used when I built my ACA....probably should check lol...

You better take a bloody photo cause on mine the brown stuff is just a glass reinforced teflon film which you DON'T use.

The light pink material is the keratherm.
