DIY GUITAR PREAMP
Diy Stereo Bi-amplifiers?
hi i am quite new to audio amplifiers. I have previously build some guitar pedals and guitar preamp/powers amp.
So now i want to build stereo bi-amp with passive high-mid filter(chip or solid state).
Some this like this.

But this schematic is quite unclear to me. Any help will be appreicated. Or can you suggest any similar circuits with pcb layout.
Thanks
that’s a strange way to draw a schematic. Basically it’s a block diagram with detailed schematics on each blocks. So you have to look at the block diagram to see how to interconnect the pieces.
And, the values are not on the schematics, so you have to refer to the parts lists. Neither are the power connections to the ICs. Nor the bypass caps.
Basically, I’d take the drawings of the schematics, add the part values, and interconnect them as the block diagram shows, so you have one central schematic with everything on it.
But that’s a bit of work, and you need a drawing application. And there may be other things missing that my quick look missed.
Edit, I can’t find any heat sinks for the output stages, so this is capable of only a few watts of power, not very much.
Overall, there is a lot of risk to an attempt to duplicate this circuit, as too many needed details are missing.
