Hi, I have a digital rackmount synthesizer (Korg Wavestation AD) which reboot after being ON for a while, sometimes many times in a row (fast) making a sound like knocking on a door. (When I turn it on it makes "toc" in the speakers so booting many times in a row makes this knocking sound).
I think it is a power supply issue because when computers have a reboot problem it's usually caused by the PS. I am unable to get a new PS because of the age of the thing so I thought replacing the electrolytic capacitors on the PS board since I heard that those degrade with time.
Am I wrong about that? What other components might cause such behavior?
I also thought trying to fit a computer power supply. I managed to get the service manual for the synth and it uses +12V, -12V and +5V, but the synth only puts a load of 0.15A at +12 and -12 volts and a load of 0.8A at +5V. I read somewhere that PCs power supply can be unstable if the load is too low.
Any thoughts or comments?
TIA
