Hi, just bought a Sound City Artiste Pro 30 Combo in good condition physically, soundwise its giving me a headache- literally!
giving out a pulsing buzz/hum and background hiss, problem being I can't find any schematics for it as its quite a rare amp, we think it might be a leaky transistor and filter cap. The circuit board itself isn't that big, theres no separate gain control(I think the tone controls maybe active- no vol when bass-mid-treble are at zero)
Anybody experienced in troubleshooting? advice welcome :(
Sorry about the long post
