help .. deepers x5 schematic

[a7mdrat]

Hello... I want to connect a normal coil with two outputs. Where to connect the two ends of the coil... As it is clear in the diagram, one end is connected to the ground and the other end is connected to A... In this case, what is the use of pin number 3 of the IC 5534

Thank you very much, dear sir. Please allow me to ask another question... Is this explanation in this picture correct?

[a7mdrat]

I want to know if the scheme is correct or there are errors?

Those are JFETs and usually drain & source are interchangeable.

Overall it's a poorly drawn schematic and I would need to completely redraw it to make sense of it. But what little I figured out on it looks correct.

Thank you mr carl-nc. . i am waiting for you

[Carl-NC]

It will be a long wait, I don't have the time to do any more with this.

Yes, it is true, but I want to solve these errors and fix them if I can
