WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
I have a small Chinese tube amplifier(Yarland) who suffers from humming when i turn the volume over 2/3. This is annoying for me and i hope there are some people out there who know if there is something to do about it(changing/adding components)
Thank you!
Hi tuberider,
What happens if you short the input and turn up the volume? Are you using a passive preamp?
Normally you would not have to turn the volume past halfway on an integrated amplifier (I am not familiar with yours). Can you post a schematic or link for your circuit?
