The transformer, is in effect, simple (no center tap), but the source is with half-wave rectified and if you enlarge the image to 400% you will see 3 out cord
thank you Mile I build this one and its very good for sub I test it with dual TDA stereo as I build before the result was great and sub is shaking the room, here the PCB with PSU I used for it.

power supply from 35v:
but I still have question about two things what is AUTO used for?
and speaker input I didn't use it just use the line in again when I can use them?

AUTO post signal to auto-start circuit, turn amp on if signal present and turn off if there is no signal after 5 minutes.
If there is no line-out connect on your audio system, you can use signal from speakers outputs and connect to speaker input on this x-over.

Hello Mile, First let me tell you that your contributions to the DIY community is priceless, Thanks for all the stuff, I just need to know how I can bypass the tone control part of ML3, is there a way to turn it off, thanks in advance.
IC1 is preamp, IC2 is EQ. Use output from IC1B out if you don't want tone controls.
Regards
Thanks Mile, Also can you post the PCB layout for the Preamp you describe on your Class A PSU thread it looks brilliant

ASK TONE CONTROLL MR APEX
I've assemble tone with potensio 2x50K controll apex.
I heard the high voice is not good but if in a low voice I feel pretty catchy.
I question whether the components that I use have to be replaced?
help me Mr. APEX.
