FAME G20D2-A

I've recently bought a FAME G20D2-A  practice amp off ebay. it was fine for a few hours use but now all it does is buzz. It's doesn't stop buzzing/humming when the strings on the guitar oare touched/earthed either.

Disconnect the cables at the speaker terminals, and measure its ends with the multimeter in the 200VDC scale, you will probably find around 20VDC there. It's a Bad TDA2050 and or 1 or more filter caps. I was replace TDA2050 and all bigin working))
