Hey all, I’ve built a few of these but I I have bumped into some issues with this one. There is normally plenty of dirt to be had.
Basically the volume and gain is quite low. I have had a look at the other threads and tried replacing the 2N7000, same issue.
I’ve worked through with an audio probe and there is a big volume drop at R13 (2m2) jumping that certainly brings back some volume, but not necessarily the dirt.
I am getting returns on all the transistors which normal for my understanding but pin 3 of Q5 shows no vaults. All resistors and caps have been checked. The back photo shows a hack up where I struggled replacing a 10m, it’s the same after as it was before, so I am happy this isn’t the issue.
Any pointers ? At what point on the schematic should things get dirty
