I found a Philips radio/record player from I believe 1968 at a garage sale. I picked it up for $5. Sweet deal for me! I researched the cabinet to find it's general manufactured time frame. I've already repaired the record player but the radio is somewhat dysfunctional. Dysfunctional in that only the left side of the unit has sound while the right does not. I checked the speakers, and the balance selection knob works. I then started looking over the PCB board for burnt out components to which I found two ceramic cylinder type components that look like resistors. I thought maybe they were capacitors, but I'm really not sure. They have "M1" stamped on them (i'll attach a photo) and a diagram that looks like an AC voltage source diagram. Circle with a squiggly line throw the middle.
I'm not too familiar with components, just getting started with this radio cabinet. I'd like to replace these but I don't know what they are exactly?
Any help would be greatly appreciated. If any further pictures are required I'd be more then happy to upload. Thanks
Edit: Thanks Sparky256, no I haven't tried an ohmmeter as of yet. user2943160: I'll attach some photos for location.
