From nothing to 2 working SIDs?? (mono6581 and MB6582)

Ok, update on the optimized psu since I finaly got hold of another bridge rectifier....

When measuring DC I get:

- 5.20V at 5V output

- 5.20V at led pin

- 14.09V at 14V output pin

So far so good but when measuring AC I also get:

~ 10V at 5V output

~ 10V at led pin

~ 30V at 14V output...

Somehow there´s AC going everywhere in the circuit but I can´t figure out why??! I use a W10G bridge rectifier but from what I understand (which I agree is not much) it should make no difference.

If anyone has an idea what could be wrong I´d really appreciate it.

Hey, just out of interest, when you put your multimeter to AC and measure the voltage across a 9V battery, what do you get?

Hey Mike, huge thanks!! You saved me from going over everything for the 20:th time:-)

My multimeter measures 20V AC across a 9V battery....I guess that means I have a functioning optimized psu for my sid!! YIHAAA!!

...mainly that means you need a new mulitmeter ;)

I guess you´re right....that´s the only thing I can be sure of. BUT...I´m still happy :) I´m pretty sure it works now. I´m a believer.

I had a sneaking suspicion your meter was acting a bit wrong.

So with a new multimeter I was able to figure out that my psu section problems were not only a broken bridge rectifier (probably from a short between it´s in/out) but also a faulty psu. And yep, the multimeter was broken also....I´m very glad everything worked out before I got crazy.....Now everything is working fine! Now wiring and uploading :)
