Does anyone have any service info or a schematic on the G-500 acoustic amp? I have one for repair with a loud hum/buzz independent of the master volume. I did observe ripple on the PS rails- replaced the filter caps- no luck. I have a schematic for the G-600, but it doesn't seem to quite correspond to the G-500. For example, the G-300 and G-600 schematic show Zener diodes in the PS- but I don't see any for the G-500. Been chasing my tail for awhile on this one- any help would be greatly appreciated.it's almost like this amp came from some weird alternate universe and there is no information anywhere on it.

"8 of 18", "19 of 22", "25 of 25" (and a couple of amps)
"Alternatively, you could just go the ultra-relic route with it. Basically go for a look that says the amp was on fire and they put it out using belt sanders. "
I have one, also not found any schematic. I think they were a short lived experiment before they came out with the fancier wood cabinet models.
