Hi!
I Have a RF T8002 Amp that is not working.
I havent been using it for 7-8 years and when I put it away it was because it was broken. Now im gonna try to fix it.
I plugged it in yesterday to see how it acted.
When plugging in B+, GND and Remote signal (without plugging in speakers or RCA)
After about 5 seconds it burned a 40 amp fuse mounted on the the B+ cable.
The amp also makes a howling sound.
After putting in a 60amp fuse the fuse doesnt burn but the cable got very hot.
The howling sound from the amp still goes on.
Those black things mounted on the wall also gets very hot (only the 4 showed in the picture, the others dont get hot)
Could those be faulty and where can I buy them?
Or can it the something else that is broken?
Appreciate every help I can get.

There are 2 banks of 4 FETs in the power supply. One of the FETs in the other bank has likely failed (shorted).
The MEHSA insulators make this repair much more involved than an ordinary repair.

Im quite a newbie in this section.
Can you explain this further? what should I look after?
Is it expensive parts to buy?
If you have pictures to show with it should be awesome.
