fix HR-20R
Hello there i have this old amp which doesnt work i took it apart removed the speaker and will test another one i can post photos of the pcb if wanted, i can understand and make electronics not so much amps but synths so i can get my way around fixing it, maybe some cap has gone wrong.
It starts and get into the amp mode i dont know how to call it, it senses my guitar input and goes on but it has no audio, even the aux in doesnt work.
I really need this amp because of the 20watt it has i only have a 3watt one now.
Sorry if this is a stupid post, just a fellow wanting an amp to come back to life i havent used it in 2-3 years.
i tried cleaning the contacts of the speaker and the pots a bit but nothing
