I have an Ilford Multigrade system for my 184 Durst that I'm just now trying to set up. The 500 SLE power supply doesn't work. The fuses (external and those accessed by removing the case) are fine. Since the power switch lights up and there is line voltage going straight through to the enlarger head cooling fan, I assume a (or both) transformer(s) are bad (no xformer hum). Does someone have a schematic so that I could put a voltmeter to it and perhaps isolate the problem? Thanks.
