Did you care to thermaly join that separate sinks. How hot they run?
Hi JC, no I figured that 3 fets on each sink would even out the heat. After 5 hours the temp 44 deg C right above the uppermost fet. Those heatsinks does a better than great job. I am considering cranking up the bias a bit, but since the amps are more than plenty powerfull, I dont know. As they are adjuted right now, they can even battle a summer-evening without sweat

Steen, wishing you and Morten a great ending and a great beginning.
Thank you Sir The same to you! I will try to draw Morten's attention to this thread

Everything is massive.
Yeah, I keep dwelling at those heatsinks. Cant tell you how happy I am to have so nice and big heatsinks Must have been a man saying that
The amps take 2 hours to settle in temp. The hottest I measured yet is 44 deg C. So They might last a few generations. My oldest son doesnt care much about music. My second oldest does though He play's guitar (and sometimes the drums) in a local band Proud farther talking.

I am sure, someday I am. This will be the ultimate amp! No doubt!
With +/-22V supply the J-fet input is within reach.
I didnt calculate anything, (Magura said: what the hell do you need those stinking calculations for?) I said: I dont really know, but I guess someone at the forum will ask! He replied: To hell with that! I agree to some extend
Take a look at those heatsinks, I really like the shape of the bodyplates.

Wow thanks a lot John You couldnt flatter me more
Here is a pic of some aux, boards They are rectifier boards and soft-start. I used Wima X2 rated polyprops as snuppers, thinking they could take the heat.

Nope I did not! The black amp: namely ´the Babbelfish, is the best sounding amp! No doubt about that! If you read my writings correctly, you will know To put things strait: The Babbelfish is still the best amp around!
