Amp manufacturers use different thermal insulators on the ps and output sections. Im curious to know why the output sections get the yellow foamy insulators. I'm sure someone on here knows.
I've seen the larger case transistors that didn't lay perfectly flat and they appeared to be using the thicker insulator to try to get better thermal transfer than they could with harder, thinner insulators.
It's possible that the thicker insulator is more conductive (thermally) but high performance insulators of that type are typically very expensive.
Maybe someone else has a more definitive answer.
