How to add a preamplifier and ground balance to a circuit diagram

[lxs17757414132]

Here is my circuit diagram
Who can help me improve the schematic

[algan]

this is the scheme of PI POLONES, but you changed it
sound circuit do you have a video how it works like that

[lxs17757414132]

I don't have a YouTube account and can't upload videos

what you meant under 'preamp'? you have LF357 and it is one. or, did you mean 'the-two-stage-preamp-gives-me-Magic-5us-FIRST DELAY-Foster-promised'?

[lxs17757414132]

It's a two-stage amplifier, so how can I add ground balance to the circuit

[kt315]

you can use SEARCH knob and ADVANCED SEARCH.
you can try to seek up HAMMERHEAD PI project, learn it, before you want to ask something.

As far as I know, this is a fake circuit diagram
