I think that you would like to use a 723 base PSU like the one used in the
Elektor Formant for instance:

(Anders site is at http://omega.tellus.vallentuna.se/anders/)

You will find the powersupply in Chapter 3. It is very simple and should not
have you face any major trouble. It's capable of delivering about 800 mA and
a typical ASM-1 is eating about 100 mA, so for a single ASM-1 you should have
a good margin and the 2N3055s will not be ultra-hot. Sounds like a treat.
Just put the 2N3055s on sufficiently large heatsinks.

Hmm... just reminded me that I have one of those PSUs to hook up to one of my
ASM-1s...

Cheers,
Magnus
