Hey,
I built a nobelium a few weeks ago and It appeared to work, but while playing through it, the low E string Distorts/ farts out when played hard. When I heard this, I unplugged the jack from the input and a loud squeal came from the speakers. I am using a one spot for power supply with 9v 1700ma.
The Bass, Treble and Volume can adjust the frequency of the squeal.
I have replaced the tubes with new tubes and still have the same issue. The sound comes out of the 1/4" output and the DI output.
