Topic: A sudden case of ground hum

[earmonger]

This is probably beyond elementary to the electronics experts here but:

I heard a sustained tone in my latest recording with a pair of mics I have been using forever--an ancient Church Audio model with Primo capsules if I remember correctly. Tested the mics and sure enough it's from them: a hmmmmmm from the left mic and a HMMMMMMMMMMMMM from the right, especially if I touch it.  Steady and sustained, probably 60hz. 

It's not in the mic jack, line-in or battery box, thank goodness.

Would this be the capsules announcing their retirement? (If so, they deserve a gold watch and a pension for faithful service.)

Or would it be in the plug? Is it worthwhile to get that rewired?

Thanks for any advice.

Time for a recable. I am not sure what mics you have I only use primo capsules in one mic that was the b99 or pro binaural mic or ca-10 as its now known
Email me a picture and I will help you out with the issue.
