Title: VOX AC30 Power Lamp Flickering
Post by: dpm309 on June 27, 2022, 01:23:04 pm

I have a weird problem with a VOX AC30-20-01. With the power switch off, the power light exhibits a faint flickering. One you unplug the power cord, the flickering stops. Getting about 38VAC on the neutral side  and 122 VAC on the line side of the power lamp with the switch off. I have attached the closest schematic I could find for this amp and it appears that something is not connected right.  This is just an annoying issue and the amp is working fine. It appears that maybe the power switch is wired wrong. Any suggestions?Thanks,Dan

Wire it like the schematic you posted.

Thanks Sluckey that did the trick. Wonder how many other AC30s were wired incorrectly.

dpm309, now I'm curious, how was it wired?
Thanks.
