Can anyone tell me the expected multimeter readings from the wires to the two speakers?
I just bought a Flextone II at a pawnshop for very little money due to a dramatic noise problem.
You plug it in, push the power button and it goes POP! POPPOPPOPPOPWHIIINE very, very loudly. The volume knob setting doesn't matter. It can be all the way down to zero and it still happens.
I took it home and took it apart. No bulging caps or anything else obvious.
I reassembled it and tried it with different speaker wire combinations. Here's what I found.
No speakers connected, listening through headphones = No problems. Everything works.
Either speaker, either black wire and the red wire = that speaker works fine.
Either speaker, either black wire and the white wire = that speaker works fine.
Both speakers, each with a black wire and either the red or the white wire = Problem's back.
Am I right in assuming it's likely some sort of short between two of the wires?
Can anyone tell me what readings I should expect from a multimeter on the various wire combinations? I'd like to test things before I just start replacing wires.
And of course, if anyone has any ideas about what else might be causing this, I'd appreciate hearing your thoughts.
Thanks in advance.
