Paul,
With a 1.4 correction factor, I might do each channel as a mono-amp. I was going to get separate torroids anyway so it's not that bad.

The circuit looks simple enough to hard wire so I was going to do that. Having built only tube amps, I have some neuorses about using a PCB.

I'm wondering if subsequent versions with ccs will need less dissipation. Or, will they need more?

Well Paul, the only thing I am sure of is this; If I was to order from Conrad, I would take the biggest sinks they have!! The biggest isnt too big at all!! I am sure it will be hot!! Please order 2 so you can make a nice chassis!!

Paul,

This sink looks more promising. 0.1C/W in a 4inch width.
