Hi all-
My M-50 seems to have developed an issue with the protection relay not clicking off(on?) it used to switch off if I toggle the speaker switch on and off a few times, but now it's not even doing that. I can get it to go off eventually if it power it on and off a few times, and play with the speaker switch.
Any ideas where to start with this? Are the relays a common failure with these, or is it a DC offset issue. I'm not even sure what the conditions have to be for the protection to go off.
Any suggestions would be helpful if someone has worked on this amp before. I bought it new in the early 80's, and it's worked fine up until now.
Thanks in advance.
Glenn
