Could my fuzz face woes be cause by the type of power jack itself?

[TonyClifton]

I'm pretty new at the whole electronics thing but i'm trying to clone an old diy germanium fuzz face that was built for me awhile back as it want a spare just in case something happens. well, i got finished with my second attempt, everything is right in terms of polarity, all the wiring is correct, i'm using the same transistors that are in the original as it was socketed as well as another set with the same gain measurements. i'm not sure whats up but it is not working. the led lights up but it doesnt let the signal through when bypassed and when it is engaged, the most i can do is manipulate the noise coming from my power supply with the pots but other than that, not a peep. my soldering is on point as is the traces as they match the exact layout as the original. then i realized that i had overlooked the '-9V' label over the power jack. i always used it with batteries and i think i only own +9v pedals besides this one so the concept is new to me. i am using a bunch of jacks for my clone that i have used for +9v builds such as a llama and some byoc stuff. could my problems be caused by the actual power jack itself as i'm using a + version insted of -? am i supposed to be using a -9v dc jack for this specific fuzz face? i'm confused as smallbear doesn't seem to stock any except the general 9v dc jack.

If there's no signal when bypassed, then the switch and/or jacks are mis-wired. Sort that out first.

Old germanium FFs tend to be PNP which means positive grounds (opposite the modern standard). No telling what you did when you added a DC jack to that circuit.

The jack itself has no polarity, there is no - or + only negative and positive voltages. If the original did not have a DC jack that may be telling you something. Mostly, people don't use those on positive ground fuzzes and such, leads to plugging into the wrong thing.

Can't do anything more at this point than suggest you sort your wiring and look at GGG for some wiring diagrams. You can

About the DC jack, I believe that you cannot use the same power supply for pedals with positive ground and negative ground simultaneously. Even if you were to reverse the leads going to the "backwards" device I think that once you plug guitar cables into the pedals the grounds would short out the power supply. Or do I have that figured out wrong?

Not that it is necessarily relevant to the problem here...
