Hello again. I'm working on a new project that will be the foundation for some transistor-based guitar effects. I have some old PNP germanium transistors that I've been playing with, but most of what I've read doesn't explain PNP operation very well. They typically go through great lengths to explain NPN transistor circuit analysis, then quickly summarize PNP circuits as simply "the opposite of everything". Well, it doesn't appear that simple to me.
Please reference the attached schematic. I've already built this on my breadboard and it's working fairly well with the following parameters:
Vs = +9 volts DC
Vin = 1 volt AC peak-to-peak referenced to ground
My question is since everything is the reverse of an NPN circuit, should Vin be placed across ground and Vin or should the ground of my input signal (guitar) be connected to Vin and the "hot" connected to Vs? Is the output correctly taken between ground and Vout or should the output be across Vout and Vs?
Please ask if I haven't been very clear on anything (very likely). I haven't played with transistors in decades (since college) and even then I mostly used them for switching.
