My JLH Evolution amplifier (09-09-01)

 

2 times 1 channel, the blue blocks are the output protection relays.

A 5 pole XLR Neutrik conector is used to connect the supply to the amp. Pins are Vpos, Vmin, GND, Relay+ and Relay-

  

Nice and hot as you can see. The ambient temperature was about 20^C.

(@ Iquiscent = 1 A)

You can see a small part of the old supply on this picture. Currently I use more caps (60mF for both V+ and V-).
I have to thank Rudy who was so kind to give  me the huge cool block, and Heino for helping me with the mechanical layout!
