Hi,
despite its name, that manual is a maintenance manual. There never was a
component level service manual for this series of analyser.

If the psu was running then I agree, change all the caps. I've repaired a
few that way. If it wasn't running then I'd suggest you also check a few
resistor values and the diodes too. I've had open diodes and open resitors
in those supplies as well.

Don't forget, Massimo can show you how to convert that 8711 into an 8712,
it's easy to do and it works. I also have a JEDEC file for the IBASIC PLD if
that's wanted, I found that ibasic wouldnt work without it.
