Pretty much as just discussed in the other thread 😉
Looking good. Fast front-end, very easy to compensate 😎
Yes, there is idea come from. I do not expect any interest for SR50R. Luxman live this topology in 90' I wonder why?
Thank you Alex, that is what i'm thinking about too. I'll try ti make it better while waiting for your great design as usually.

look at the gap between +ve supply, zero volts supply and -ve supply.
These big gaps will insert big loops into the supply wiring and as a result emit excessive EMI, causing avoidable interference.
Now look at your supply rail decoupling: where is/are it/they?
Do they have long inductive traces?

SR300 rail voltage
Hi Mr. Mile, what is the max rail voltage supply that can be use on SR300 and the advantage from SR200?

newest attempt of SR300 pcb,added APEX controle(power-signal-clip) and APEX-protect to the board. i tried to draw as short as i could all small signal traces and also tried to avoid electro-magnetic circle made with copper traces with large currents,that is why i used three PGND places on a pcb. all of those large current traces (as i could see) are as short as possible,and do not share any current from other (positive/negative) side across the PCB,and they are placed shortly up to the right/left upper side of PCB pretty much away from input stage. all grounds from input stage have met together at one point-at one end of 10r resistor (no sharing currents) whose other end is connected directly to the GND of PSU. i avoid to put Zobel inductor on an amplifier PCB or any inductor if possible,so there is aditional small pcb wich contains protect relay anz Zobel R-L and R-C so one can use it together or wich ever is prefering.
it is not been checked out yet but it is a work in progress...
(untill it is not checked in practice i will not post any other files)

Sir,
Please send me the link of pcb for PSU-10 required for SR200.
I need help for PSU selection. I will use SR 200 REV 3.2 pcb.
