You can't

My heatsink is the same cm^2 as your first one about and the same schematic.

Iq is correct, I wonder why it cooks?

Dang sand!!!


Cheers!

Hi Geek!
My first pics is the original SEWA with CCS and 30Vdc.
The heatshinks are ca. 50C., but my whole case is made from 5mm aluminium. So the case itself a big heatsinks.
Do you have some oscillations??

No oscillations, but didn't take into account the case. That would likely do the trick.

I just need a bigger sink then, because I was going to make the SEWA into a piece of furniture with hardwood fretwork and little exposed metal

Cheers!

Hi meanman1964!

First you have to finish your tubepre and Choke loaded amp and write here your listening impressions.
After we can speak about it...
