I have a problem with “hot tubes overdrive” of you which i used to use a lot.
it appears that the inner torodial power transformer from 10v to 220v (“Taiwan torodial technology inc.”)
, outputs a low output of 60v, and the pedal gives a very low volume and strange cut sound.
I turned to a few technician here (israel), and even tried contacting “Taiwan torodial technology inc.”, and I have no info about where I can get this part.
