Refinishing MMATS amp *pics*

Pinhead-Just pulled apart my MTX amp and you are indeed right, there is a small black strip under the transistors. [img]graemlins/beer.gif[/img] however...
Now heres what I don't understand...The backs of the transistors are metal, the plate holding them down is metal, and the bolt holding the plate down in screwed directly into the heatsink...?
Check the pics in the link I posted above.

kilo the clamp is touching the plastic not the metal
the reason there is an insulator used is the tab or casing has voltage
your output transistor have a positive side and a negative side
one will operate with a positive voltage and the other will have a negative voltage
as well as the power supply has its own voltage to and you also have your rectifing diode so they must all be isolated
i have seen one or two without insulators on some of the trasistor but that is far and few between
in the picture the bottom 4 transistor to the left do the power supply
now the 2 to the right of them would do the positive or negative speaker output
the 2 to the far right would be the opposite of the transistors beside it
