Yamaha Rev 5 Power Supply pinouts/voltage rails?

[OlympicPhil]

Hi,

I've got a Rev 5 that's a bit ill. After "repairing" a dodgy diy power supply the unit won't boot up. The screen lights up but nothing appears on it.

I'd like to check the voltages on the power supply but I don't have the voltages.

Can anyone help?

Thanks in advance,

Phil

A Rev 100 was 9v DC...
BTW - could it just be a dodgy EL panel that's gone?

ah this rev 5's got a 5-pin din power connector. I need to know the pinout so I can check it.
The transformers inside the psu are kicking out (post regulators) +18VDC, -18VDC, and 5VDC but I need to know what pins they should go to.

Ah, this one must've been modded somehow, I've traced it from the board now and mine's -18, analog ground, +18, digital ground, 5V

Thanks for your help though
