Default Re: Kit 34 tubes change bias

Hi Richard. The sound is like buzz with mili break every second. The buzz sometimes has gone like just now when I write this. It happens after several hours of listening. Changing selector doesn't change noise and volume level has no influence on it too. Any idea?
Thanks for help.

Change inputs and try them all.

What kind of noise is it; hum, crackle or rustling, whine, etc?
