What's the use of power amplifier mica slices?
Of course not, the amplifier heat sink is generally directly connected to the collector of the high power triode, and the outside of the large heat sink is generally grounded, so without insulation, it may short-circuit the ground, burn out power amplifier
Some power and power amplifier modules with metal heat sink, and the internal circuit is connected, so mica and radiator needs to be separated.
Metal pipe and pipe behind the collector is connected if there is no mica all even to a collector of the anode NPN tube collector POWER PNP tube collector tube without power supply directly short circuited mica sheet
