Hello all! I am working with a simple half wave rectifier circuit for audio purposes that uses only one capacitor and one germanium diode. My goal is to have the ability to output either phase of a waveform and also combine two halves of waveforms to create a new wave. I get results of either a positive or negative half Of a cycle but do not see how to split the output for an either/or result not can I send signal the opposite direction without blowing diodes. Parts to use:
3x 10k resistor
2x 100k resistor
2x diodes
3x 3.5mm female jacks

There is a piece of gear I am basing this on, but was hoping to modify once I get the proper circuit.

Thank you for your time and consideration!

Does your transformer have a center tap?
If I understand you correctly you want to make a positive and negative supply. Is that right?

You understand me correctly, but this bipolar half wave rectifier does not use a transformer. I'm sorry if I'm not forthcoming but I am unsure of what I can and cannot say here as of now.

Germanium diodes, are you talking about SSB modulation, that uses upper and lower halves of the signal, and a bfo for the receiver?

Dodgydave, I do not think so, at least. Here is an image of what should be almost half of this thing:

Hope that worked... I'm not very forum savvy. I need three inputs one of which will give me either half of the waveform out from the other two and the "half" inputs can be combined to create a whole waveform out of the first input.

I am ill prepared to upload my own images...

If you could imagine this as a signal it is closest to what I'm trying to achieve. Splitting two different signals in half and combining the halves. I don't think a bridge rectifier will give me this as it maintains a constant dc voltage, correct?
I know most are probably thinking that I shouldn't be asking others to do my work. I've been on it for weeks now though and have no luck, but have witnessed this circuit in action from a diy source. I am out of leads.

You're not making sense, post a circuit diagram,
are you talking about a ring modulator, like in a ssb transmission or dalek voice?

I know, my diction is rough at best... I apologize. It will be this evening after work I will post what I have so far and remaining questions. In the meantime please google search "bipolar half wave rectifier" if you find the time. There is no such completed or readily available diagram.

If you have two half-wave rectified signals you can add (combine) them using an opamp. However, the result won't look like your post #8 sketch unless both signals have the same frequency.

I want to use opamp once I get to that point in order to reduce voltage drop and therefor maintain my audio signals. When I try to send signal "in through the out door" in my simulations diodes explode every time. Images to come.
