Title: I’m stuck—275vDC [resolved]
Post by: Allen on November 16, 2024, 09:24:42 AM

I am building an Eros. I just completed the power supply board. Checking the DC voltage, all is good on the 6.3vDC tabs.
But I am getting nothing at the 275vDC tabs.

I’ve checked my solder joints, everything seems solid.
Where do I start trouble shooting from here?

Many thanks,

Allen the Noob

Post photos of your build so far and we can have a look.

Thank you.
I did powder coat the plate, but I also cleaned it with a drimmel and acetone wherever a metal part contacts it--bare metal on bare metal.

You are missing some parts on your power supply PC board.

These will help a lot as well.

Found it. I overlooked that step probably ten times going back through my work.
vDC tests right. Thank you again
