Great work. Thank you. Saved me a few hours redrawing the circuit. How about creating the gerbers now?

the upper output of the volume control is connected incorrectly

Thank you Artyom.

Volume control pot corrected. "volume" added. Sensitivity control pot corrected. "Sensitivity"
"Zero Filter" added.
"Ground balance" added.
CD4053 pin assignment numbers added.

No thanks.
Somebody else can have a try.

Sent you a PM, if you could clear some confusion please.
Thanks

I only redraw schematic. Question about circuit is better for the one who put it.

My observation is that it implements a rail splitter circuit by means of a 741 opamp. Such a circuit is used to make a split supply (positive and negative rail voltages) from a single supply.

The ground seen in the schematic is commonly referred to as a virtual ground and in this case it sits at 0 volts.

These type of circuits are very well known.

I google it.

A very well working detector.

My question was answered elsewhere.

Thank you for your expert advice. That all makes sense now.

Hi bgs
Do you have set-up and calibration instructions?

Hi bgs,
Looking at R16 on your schematic. What is the purpose of this? Is it a potentiometer or a trim pot ?

Dear dbanner!

Looks like a spider's web that drank barbiturates!
Terrible!

Show me a spider who drank barbiturates and I'll show you Jimi Hendrix.

There is something wrong with a Man who can have such beautiful ideas in his mind, but behaves such that nobody can understand your drawings.
Monet does not come to mind.

Perhaps in the next century, a bgs schematic will auction for millions..... perhaps
