I recently spent many months agonising over my amp which was making static like noises , only when using rca output . we are pretty sure that mains noise was causing this as once I caught it doing it with the washing machine being turned on
the valve amp repairer found everything to be absolutely brilliant and working but that noise was getting in via the rca output. so he made me a little cable to attach to the other rca output and ground to the chassis and its been sounding fabulous ever since .
hope yours is rectified soon as it drove me BONKERS
ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down
