This noise is a low level "popping - crackling" noise.
I have subbed all the tube.
The noise stays the same regardless of input or output gain.
It is intermittent.
I have heard that resistors can cause noise like this. I would like to try the "Grid/plate resistor subs.
Red circles 1-2 are plate resistors? Where is the plate resistor for the V407 output tube? in green.
The blue circle, is that the "grid resistor"? could it cause a popping noise? It looks stressed.
Is the purple circle the plate resistor?
Any other thoughts?
Thanks!
