A little more OT cant hurt It isnt easy to get a good shot of the output section, but here is the best pic I could take. Check out the FB lead, its pink My little nod to board designer Pinkmouse.
The heatsinks measures 400x200x80 mm and weighs 9,2 kg a piece. The bodyplate is approx 16 mm thick.

Re: Heat
Hi Jozua
About 45 deg C , above the output transistors, on the heatsink. Thats with the amp being turned on for at least 3 hours. It takes a long time to warm up completely.
Psst, Choky it would be more fun if we had some Pumpkin talking to do....

... It doesnt come close to an Aleph-X or a F4, when it comes to musicality...

Steen, nice work! I guess that you had to build it just to convince yourself how good an F4 sounds!
Now back to Pumpkin...

Thanks Vix. Excactly. But it would be much easier to compare fine poweramps, if we had a good preamp

Yeah,
Something tells me we're not gonna see that thing till after 21-Oct, or maybe on 31. Entepreneur Choke-ster is playing it right

Entrepreneur - someone who grows more pumpkins than he needs for his own personal consumption and than makes the rest available for the open market (by the means of clever advertising such as participating in Burning Amp Festival) ether as raw material (board only) or as finished product - pumpkin pie....uups ....preamp.

I have some small doubt's about schematics, so it would be nice, having some experts checking it out.
The files i have is Diptrace schematics + Diptrace PCB layout.
Please feel free to reject me...

You're right but he needs 20mm...orange won't cut it inspite of name...but I believe a Pumpkin's flower color is indeed ultra bright pink.
