Stupid, i put the meter in the wrong position, it works now.

I checked the fuses and they are all okay.

And the story continues, but this time i seem to have screwed thing up badly:

The people from klov told me to adjust the 5v (which was too high), when i tried doing this and started the machine again i only got 0.64v. And i can't bring it back up because adjusting the pod doesn't do anything. Could it be i blew something? The fuse on the power supply board is still intact.

Still have to get a new power supply board, rebuild the old one or get a switcher power supply, but now i'm afraid i damaged the machine even more!

What was the procedure ?
i understand when you say , "started the machine again" that you are twisting the pot without power ?

anyway , just tell us what you did exactly please

First i twisted the knobs with the power on but nothing happened, the voltage stayed the same, so i turned the machine off and on again..

That's right but the people on klov told me that this is a common problem:
The pots on the PS get flakey. It is possible the wiper on the pot broke off when you turned it. Pretty common failure point.

I still think i damaged something, kinda sucks, i'll check everything again this weekend.

Yes, but i still will need a new supply because of the missing 12V.
And just to be sure, when you say pot you mean the part that i turned?

yes sir  ;)
it should look something like this :



these are all potmeters, just the housing is different

or you can take it out first and use the ohm meter on your multimeter and check if it is broken

I also have a switcher here for you (which i am not using atm) if you like to use that as a test..
hmm  hilversum, when will i be there again  ;)  maybe when it snows  ;D
