channel imbalance freak out


I did some long overdue vacuuming in the hifi rack area. What a mess! Disconnected cables. 

Reconnected everything. Very low output right channel. Start the troubleshoot process.  Do the simple, obvious checks. Go further swapping tubes -L/R etc.

Close inspection on the amp speaker taps  revealed a ONE STRAND of the REL subs negative cable(bare wire) was touching the positive tap! Whew...I was only thinking how about the back strain and WALLET opening for the repair!!

How many times is a perceived problem, just operator error?

millercarbon- good points.

This operator is guilty of MANY errors!

The cable management thing indeed can induce noise which flares up the audio nervosa. 

I had turntable hum that I thought was one of those "it's just the way it is" noises.
A simple rerouting of the IC's s AWAY from the amps power cable made for ZERO noise!

The speaker cable lift thing I keep giving a chance to convince me it's legit for my system. Still not hearing a difference. My hearing just isn't that sensitive.

I don't live on the beach, but less than a 1/4 mile from it. I have to keep ANYTHING sensitive to moisture maintained. I have to clean my 1966 Mac MR71 tuner's chrome case to prevent it from rusting, everynow and then. 13 tubes and lots of nooks and crannies.
