Hi,
Perhaps someone here could give me some ideas of how to solve this issue. The amp is a new build I just finished. After working through a few issues the amp ran normally for about two hours.
It now buzzes when I play the low E string on the guitar. The issue is in the amp. I have changed speaker cabinets, guitars, all the tubes, and changed out most of the tone stack. I have been over the amp pretty thoroughly. I have sort of run out of ideas. I can not see any issues on my oscilloscope at any point in the circuit.
The issue is gain sensitive, both on the guitar volume control and the amp volume. Increasing the bass pot control also makes it happen quicker.
Here is a schematic...I do not have the tremolo circuit built the same exact way but I have V1, V3, and V5 tubes removed.
Thanks,
Billy
BTW, I can do most any troubleshooting and can post photos/video ect.
