duff cartridge

[jackg]

Moving Coil Audio Technica OC 5 about 10 years old used infrequently.
Fired it up today and only one channel worked.
Fault found with a multimeter.
Pins red and green (left?) have a resistance of 12 Ohms, where as it is infinite for other permutations.

So is it screwed, dust or muck in the coil perhaps?

if the blue and white pins are open circuit its U/S.
a word of warning though................. it's not a good idea to use a DVM on a MC cartridge windings as the wire is so thin you can melt the strands.

I wouldnt have done that myself.
