Ahhh sorry...my English must be rubbish!! I totally misunderstood your answer...sorry!!!

Thanks for the fast answer. Well I did read there and it says the PSU don't work good with out load...
I have taken it out of the ST. It looks very much alike the sr98

I got myself a Mega St2 and it doesn't power up at all, nothing at all happens. I thought I would start with the PSU. It has a Mitsumi sr188 Psu. Will the PSU start without load?
