Anyone ever deal with the power switch for this 41-608 Code 122 model? I understand it's used on other models as well.
I found an intermittent short in the push button switch that actually caused - blowing out the Y74 Rectifier Tube. (another on order.)
I had plugged the radio into my short detector and everything was fine. So bypassing it, I was playing the radio just fine while turning my attention to the work needed on the (disconnected) record player. Went to turn off the radio and the button didn't feel right, dial lights flickered, and I pulled the plug as quickly as possible, but I saw the flashing in the rectifier tube.
Testing the switch leads after disconnecting them from the rest of the radio, I could gently tug on one of the wires and depending upon how I moved it, it would open or close (or my meter would bounce around) when the the switch was closed (on). Anyway, by gently pulling on that wire for testing a couple of times, it came completely out. The wire's insulation looks pretty black (burnt) where they enter the switch.
It looks like this is not mounted so as not to come off the push button assembly. Carefully probing around the plastic black case, it appears it would lift off if I drill off the two metal grommet tops just to lift the black case off I can access the terminal points for new wires. But I'm not sure if those metal grommets are holding the entire switch on the assembly.
Anyone ever deal with this? I'm guessing a replacement part is impossible to find. Any comments, ideas, etc. welcome.
