Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

hi , I build this circuit and its working fine,

I did not have a 50v 220 uf cap so I put in a 16v  470uf.
even though it is working good could that give me any problems over time?



I also  wanted to connect some led,s for monitoring .
I did connect some led,s with a transistor  to pin,s  3,2,4,7,10,1,5,6 and to neg.

but having no joy,

I was full sure that should have worked

just wonder would the output pins supply enough current to switch the c945 and an led at the same time

any help appreciated


thannk you.
