Hello,

same thing here, ISA428 with problems at the powersupply. Does anybody have a schematic (or the voltages of the PSU?)

Thanks
Frank

Might as well post some photos of the psu, at least? Even without a schematic, at least topologies might as well look familiar to some of us...

From memory I think the PSU was just a pretty standard LM317/337 linear supply.
