Well, it shoud be until the PSU gets going :-).
Right
I presume that delay is that 47uF capacitor charging
up. So
that's probably
not defective.
Yes, is this delay. I have change the capacitor with a new one, to be sure
of this delay ... but with no effect
Maybe IC3001
or IC3002 defective ?
Or the transistor is open-circuit? Still, you're now down to one simple-ish stage
that presumably you can
debug.
Yes , the only question is : what is the tolerance of these protections ?
Incidentally, I should get a copy of the schematics to
Dave at the
weekend for scanning.
They are good ! very good.
I'm writing a little page with information on how to repaire this power
supply, and can complete.
Thanks
Alberto
