Rangemaster (Im new to pnp transitors)

[Domin]

Hi! Maybe its stupid question and maybe its somewhere in the forum but...i made rangemaster with OC44 and Im not sure how to wire it...I know how to wire pcb but in and out jack terminals which are most of the time connected to ground, in pnp are they still connected to ground or to + of battery? On some schematics i saw that rings of jacks are connected to +9V so to + side of battery but how about other parts of signal chain or it doesnt matter? And where should be connected pot if Im using it as volume control after output cap? Which of those wirings on pics is correct?

easy peasy. in and out jack sleeves are ground, always. output volume ccw will be ground, unless special design. points on the circuit diagram will be nominated as ground as well. ALL grounds connect together, that's the easy part. using pnp with positive ground? easy, the positive [battery, external DC] is ground, and we connect ALL the grounds together. that leaves the battery/DC negative, which is now Vcc, connects to/at the top of the schematic/circuit diagram, where the collector is usually drawn by convention.

if you want to do the ring/sleeve supply switch-off, the battery circuit is completed when you plug a jack in, shorting ring to sleeve. so wire the sleeve to ground, as ever, and connect the in this case red battery wire to the ring terminal.

but don't daisy chain the supply with another negative ground pedal, is all. audio doesn't matter, cause all grounds connect together.

So if I understand it correctly, just need to solder everything normally but reverse wires from DC supply, that means battery? Nothing special about it? First picture is correct?

yeah, that first one looks fine, as to the bypass scheme, battery, jacks. I didn't take time to check the circuit out though.

Not having DC jack means not having to worry about daisy chains and power...

Ok, ill rewire it Thanks



There is closeup of layout and photo of board if somebody is interested

I think you are OK...I had to look and noticed you have changed from stock circuit by putting fixed C Resistor 10k and, the pot after that 10n capacitor as a voltage divider volume control...

I put input caps on switch too, i want to use it with bass
