Anthony,
What are you doing? So much heatsink for a mini-A? I know ... it's fun.

I did have some trouble with the PSU in CRC configuration. I was using 5 x 50R 5W Ohmite rsistors per side = 10R @ 25W.

DC before the resistors under load was 32VDC and after 14VDC across both rails. I tried removing resistors until I got to 25R per side now at 10W and still got only 16.1VDC. I have shunted the Resistors for now with jumpers across the Inductor Pads so I have no CRC or CLC, just plain C.

I am thinking something in the order of 50R is required or 5x250R

Sigh more Rework...

Actually this case is a temporary home, sort of a pilot project to determime how much Class A power I could pound inside.


So what am I getting out of these Mini A's 10Watts?

Fan is not hooked up for this application.


Regards

Anthony
