It shoudn't be a problem.

What about the idea of adding cascoding as metalman did? This could be done
pretty easily and if you dont want to "cascode" you'd simply bypass it with a jumpwire.

Any thoughts?

The boards are 99% ready, i just need to do some final cosmetic work to the silkscreen.

Have been watching this thread without comment

But now I have to jump in to say

very nice job!

it could also be made single layer (with only two jumpers)

could you post a schematic ?

I might consider trying a proto using printer transfer film.

but ha who am I kidding I allready have an aleph 30 , a

1541 dac and a TQMT speaker project all underway.

The only downside beeing that the board is rather big, 170mm x 100mm. Also i'm going to use the toplayer as a ground plane.

We'll go with the cascoded board, right?

Hmm, sorry to ask, what are the advantages of cascoding, compared to the original board?

Update:

While my mother in law desided to come for a visit i desided to go for a business trip so i haven't updated the board until now.

I still need to figure out the advantages of cascoding so i'm going forward with the design i started with. The sinks are now turned 90degress, i've added a 22uf cap to reduce noise from the zener and added a groundplane on the toplayer.

I'll have a look at the pwrsupply this weekend too.

I should get some estimates on pricing beginning of next week.
