In Reply to: RE: Are 6SL7GT or 300B or 211 tubes noisy? posted by AudioDwebe on December 22, 2020 at 08:52:00
Is the noise a tube noise - like a rushing white noise, or ringing from microphonic?, or a spitting - sort of random?
Those would definitely be the tube - and most likely the 6SL7GT
Or, do you have a hum...?
Happy Listening
Follow Ups:
Not sure how to describe the sound. Not pinging of any sort. It's not random. It's constant on both sides.
It's between a buzz and a hum sound.
I tried using PS Audio's humbuster but no help.
I've got the amps hooked up to a Running Springs Audio Maxim.
It was suggested by Cary to lift the ground. I've not done that yet.

Lift the ground and see what happens- One amp only-
Happy Listening
Lifting ground silenced the amp.
Now, to try and figure out how to achieve the same result without a cheater plug.

Purchase a pair of Ebtech HumX. It will safely eliminate the ground loop. The 805B power draw is within the safe limits of the HumX.
Well, that was simple.
Good luck in the search for a more thorough fix.
cheers,
