Hi all. 

I recently found a non functioning TC Electronic G Natural unit, that i don’t know its story. 

I tried the voltages on the main board pcb and they were very low (2vdc and 3.8vdc instead of 3.3vdc and 5vdc respectively on the digital side and -11vdc and 11vdc instead of -15vdc and +15vdc, respectively, on the analog side).
