Wow! That looks really fresh. Sorry about the slip up Salad. I just noticed that the trafo I was looking at had 300ma rating not 30. My bad, although it seemed to work out in the greater scheme of things.

200VA for this is super royally mega plenty. You would not want big trafo magnetic field very near though.

I had planned on seperate PSU enclosure with CR->umbilical chord(1ft)->C, SSHV2. 200VA was only 5$ more than 100VA.

Keep the CRC very near to SSHV2 in the main pre box.

I was under the impression that when doing a standalone PSU, you do most of the filtering away from the main chassis, with only the last C inside before regs. Do you suggest just the trafo on a standalone box?

The trafo, the rectification, and that's it. If it was CLCLC or CRCRC it could go 50%-50%. Its better to fully filter what comes riding on the umbilical too if using simple one stage filtering you see.

I breadboarded one. Sounded great already on the plank with AC heating and and a dual C-L-C-R-C-L-C. Very little noice and some tiny trafo noice with the ear in the cone.

Gonna tune it up when I get parts for SSHV2.

best
Staffan
