This is how it looks so far. Going with 10R resistors on this one (also have 3R3 version). Hope it works when I fire it up

What are the white pads under the fets? Those things are thick!

Walter,

Very nice build. Where did you get the heatsink? Do you think the heatsink will handle 3R3? Will you mount it flat or upright?

Vt,
have you inserted thermally conductive paste to the interfaces on both sides of the Al ox ?

Wow!

It's a great looking build with a very good selection of components, except one thing:

Panasonic FCs for the 100uF decoupling caps...

If you use Cerafines or, if you can find it, Blackgates it would be perfect

The heatsink I already had and is from Conrad. For the 3R3 version I'm gonna order one that is 50mm wider and 15mm higher (200x150x40).
The idea is to mount it upside down in the topplate of a housing so the heatsink is facing upwards.
