Jean Hiraga Super 30: MOSFET version

[hydrovac]

Hi all!
Current project: JH Super 30 MOSFET version build log...

The modules

The heat sinks weigh 7.5 kg each

The PSU bridge and Amp module share the same heat sink.

36 vdc rails... presently biased @ 1.5A

26-0-26 sec Trafo and soft start.

The case/enclosure/chassis

Back panel with a small fan.

You build so many of them with perfection and passion that it is Drishyam for eyes.
What happens to previous builds once you move to new one?

 

[hydrovac]

Nothing in particular... they just sit on racks watching me build new buddies.

Hello Sir,
I know that those transistor's must be getting extremely hot(boiling water point) but why such big heat sinks, you could have had 2 cooling fans for each channels (1 each) its just my view and suggestion, have nothing against your current design and your project would have been slightly smaller and lighter. regards carl
