Hello forum...
I am seeking advice as of what could be bad in the -12v voltage on a NovaDrive pedal I have on my bench...
all voltages of the pedal seem to be ok except the -12v witch oscillates around -0.1v to -0.7v, and +12v witch reads 11.09v.(I believe it is taken down by a problem with the -12v part of the PSU....
I have attached a picture of the psu schematic...
from this image:
Inductor L5 and IC3 (CS51411E) are very hot...
L6 reads 2.5ohms and I think it should be lower as all other inductors read below 0.1ohm.
I wanted to unsolder L6 to check if the problem is in the psu or at some other part down the -12v distribution but I haven't been able to do it yet....Will try again tomorrow..
Any hints on to what I can measure before trying to lift SMD stuff from the board is super welcome..Especially as this is my first attempt with SMD stuff..
Thank you
