Hello! Just received a vintage Technics SA-500 and it got a little jarred in shipping coming from the east coast. In fact the plastic fuse box cover got cracked in transit so don't know if that's related to the problem (i.e. being jarred/smacked) but...
Connected speaker wire to the two FM terminals in back, spitting the top 3-feet into a tee for a dipole affect. It picks up stations fine... BUT...
In FM/stereo mode the red LED stereo light comes on and the meters register a great signal... and I hear a great signal... for only a few seconds then it goes dead, (not like loss of reception or crackle but dead) and stays dead. If I flip the switch to go FM/mono it plays fine.
So I turn off the unit.... flip the switch back to FM/stereo... turn the unit back on... and again it plays a few seconds wonderfully before cutting out dead again.
Now since it takes a second or two for the speakers to start playing, once or twice it went dead before I actually heard anything come out of the speakers (but the red stereo light was on so I knew it was GOING to work if it had lasted long enough) and in those instances I hear what sounds like a soft click from inside the receiver. I'm sure it happens every time it goes dead, but when music is playing I can't hear it. And when the signal cuts out the red stereo light goes out of course. Meanwhile the meters that measure signal strength are strong as ever.
So that leads me to believe it's a fuse tripping or something... but when it goes dead I can still flip the switch to go mono, and both speakers still work.
Anyone have any idea what would cause this behavior? CD player and mono FM/AM plays normally. It's only FM stereo with the problem.
Thanks for any guidance. Like "Shultz" on Hogans Heroes, I know nothing!
