SC-3000 / SF-7000 repair
Post Posted: Sun Jan 03, 2021 4:23 am
Is there anyone based in Sydney who could help me to repair a faulty SC-3000 and SF-7000?

This is a video I made of what it's doing which probably just made it worse. https://vimeo.com/393641185/95a48e4309

Just some ideas:
Check the powersupply w/multimeter to see if its delivering clean voltage.
If that's OK, check the voltage regulator(s) & caps - especially around the regulator and in the reset circuit.

I'm in Adelaide so if you happen to be passing through and can be bothered hauling a SC-3000 and SF-7000 on your travels I'd be happy to take a close look.

Do you mean for the SC-3000 or the SF-7000?
