-2x30v switching PSU from a linn music system (doesn't sag at all, doesn't run hot)
-DIY PCB's, as small as possible. the way i always make PCB's

(i've committed a small grounding sin in this picture, but there was no hum so i left it like that for the testrun)

and it sounds lovely. i will run the final casing with some slow and silent fans because this heatsink isn't up to the task for normal use. for short tests it's just enough.

It is funny you are talking about switch mode power supplies.
I just bought 2 x 500W switch mode power supplies today just to see how they go.
I have been wanting to try this forever and today I bought a pair.
See how they compare when I get them

Hi, got a pair of that pcb once on my desk, I think you'll have to change R11 to 1k multi turn trimpot, may be paralleled with 400R, good luck

You can find some pics of the Aleph J construction. I made the J for a friend and for now he appreciates it very much
