I'm working in Japanese company and mostly our products are not using MICA insulators anymore, Sil pads are widely use nowadays.

I'm using silpads as well - they still have quite a nice thermal transfer characteristic. It's a matter of taking them into account designing heatsink specs. I love 'em.

Meanman,

I don't believe that setup at low speed with such a small sink will cool the outputs at such a load, well from past experience. Anyway such a setup was not an option for me , i needed a tall case and did not want a fan running constantly.


Why not the big sinks, it's not unprecedented ..?


regards,

They're nice heatsinks. I plan to passively cool my amp as well, they'll be reasonably big at approximately 0.0135 K/W. They will form the sides of the case and the PCB will be designed to be mounted to the back of the heatink. All TO220 semis along with the outputs will be cooled by it.
