hum in system, ground loon? 60hz?

Ok Jtinn, some progress. I lifted the ground on the vk60 with a cheater plug. No change. Used a extension cord and plugged into a different circuit, with/with out cheater plug. No change. On a whim, I pulled the interconnects from preamp to amp. Hum doubled or tripled. Seems like it is in my amp now. Bad tubes? Old tubes? Something else in the amp? I've had the amp for just over a year now.

Thanks

Hum should probably get quite a bit louder without your preamp or source attached. Is the hum out of both channels? Can you jump pins 2 & 3 on your amps input? If you still get a hum, I would send it back to Victor and the boys at BAT.

Hum is the level on both channels. What use alligator clips and wire to short? and which ones are 2 and 3? I think it's time to call my dealer and let him help. Thanks for all the comments!!!

I agree with Cornfed Boy that if indeed it is a Ground Loon you must shoot it before it mutates into human form. However, it could also be a Systemic Snipe, in which case you will need to have a Snipe Hunt...and there ought to be plenty of advice on this forum to lead you to Infinity and Beyond.

Hey Ned, keep it on the topic or go back to your Walkman.
