Nuuk: yeah, neat and very compact
motherone: yep, these are Socket A heatsinks. Got them from a local supplier for about 3$ each and they even had fans! Though they were very noisy and as these heatsinks proved to be quite effective up to about 50W output power, I decided to get rid of fans altogether.

Lucky you! I've been looking for copper socket-A coolers, but haven't been able to locate a deal like that. Most of the suppliers out there will charge you more for the shipping than the heatsinks cost!
You'd think there'd be some good places to get stuff like that here in Seattle, but I must always miss the sales where they clear them out

This must limit the choice of components based on physical size. Could you give a rundown of the amp components for those of us who can't yet tell a capacitor from a resistor.
Sure, I'll post the schematic soon. But there's nothing special, usual NIGC.

Yes, I have thought about that. I have even experimented with simple epoxy glue and an insulator (paper towel - about 20microns which was too thick, only appropriate for 30W or so. Sliced mica should do better but I haven't done any experiments yet).
Anyway I will use screws for this project as these heatsinks are a bit small (+-35V supply) and a good physical contact with the case could provide additional heasinking which is important as I'm not planning to put any fans there.
