Tube Amplifier Power
I have a Vox amp AC50CP2. When you mount the volume I can get a strong chirp.?

This only happens when I play. I know that is the Power Tubes, I changed out the screams and was long before that changed. Could be a problem pre-Tube Amp? What pre-Amp Tubes are recommended? Thank you, John Rossman

It seems that you have a problem of information. Put the speakers in another room and close the door. Go up the cry and see if that happens. If not, this confirms the problem of feedback. This could be a mechanical response, in which something the audio really strong vibe in the high gain amplifier stage. If you want to play guitar or similar, strong audio could enter any what instrument is playing and make comments. You just need a little space between the speakers and the instrument in this case.
