Hi,
After much procrastinating I opened up the brain, looking for obvious signs as to why the Hi-Tom isn't working & can't see anything -no fried components etc. Spent an evening trying to follow the circuitry using a bright light, magnifying glass & schematic but nothing obvious.
So not sure what to do now. My electronics isn't up to diagnosing this kind of stuff. Is there anyone on the UK who does synth repairs or a related business?

Also, just putting it back together and found that the schematic I'm following doesn't show (or I can't find - entirely probable) the connections to the power switch. I nearly took a photo but thought "it'll be on the schematic". Oops. There are 4 pins, 11, 12, 24 & 25 and the mains supply, blue & brown then orange & black going to the transformer. Can anyone tell me which way round they go. Many thanks.

Any help would be greatly appreciated as I've just started on fills in my drumming lessons & it's unsatisfactory doing them with a dead tom.
Cheers
Jonathan
