Question about Yamaha Electric Guitar
I have a Yamaha G100-212Guitar Amplifier. It didnt work when I first got it. I replaced both of the power output transisters.Powered up and played the guitar for about 5 minutes. Then I turned it off and I turned it on again there is this loud humming noise.
I have the schematics. Any suggestions whats causing the noise?
On power up my kurzweil micro piano has no audio out and loud hum

I would also be inclined to check all the larger electrolytic capacitors in the power circuits as well for AC bleed.
