Let's continue:
I made additional radiators for the electronic filter from the remains of the radiator. Now there is a radiator with an area of 324 sq. cm. but in the amplifier case this will not be enough for cooling, so I made another radiator of 108 cm2.
now the total radiator area is 540 cm2
this is already enough to place the electronic filter unit in a closed amplifier housing.
