No, im build only D14 (A100) and AX14 (no more about 120WRMS) - don't have trafo more that 42VAC for more power, and now i think to build SR250 (i have printed toner and i think build or not) or D200/500 and must have SMPS (little price about standard toroid the same power), i cloned pcb APEX SPS-1000 but i don't know is tested or not? Dont have scope yet. Im waiting for good offer (at little cost) something Analog Hameg or Tektronix.
Im only hobbyist
P.s.
I need amp for Beyma SM-212 (350W RMS 8 Ohm) https://www.beyma.com/products/lowmidfrequency/112SM2128
Any sugestion ? I must build amp too 350W RMS 8 Ohm ?

Hello xrk971
greetings FH9HV 50 volt rails+/- i will try it tomorrowi have all compnents
in the year 2000 i had purchased these hexfets matched them for anthony
holtons AV1000 AV800 FH9 is a very nice sounding amp many thanks to you for
building it and special thanks for kashyap for very nice pcb design
warm regards
Andrew

Sorry I have been lazy and not updated schematic since the sim.
The main changes in implementation vs schematic is MPSA42 VBE multiplier is exchanged for BD139 as it had convenient mounting hole.
For FH9 HV change BD139 for KSC3503 (2 places) and BD140 for KSA1381 (1 place). Make sure all electrolytics and bypass caps are rated 63v or higher. For feedback shunt cap, lower 16v rating is fine, I use a 35v one there.
Hello
greetings anyone have this apexaudio pcb design

On Apex's Facebook page he says that is AX11. However, looks like several parts have been exchanged. That's a tiny Vbe multiplier that's hard to mount.

Andrew pcb layout is similar to Willy's and Juan's layout.
You can request sprint files from them and edit layout to to make it same size as pcb on picture.

I sent you a Facebook link to the author of this layout.
I noticed you don't have 100pF caps next to the drivers. There was a newer version of the PCB by Sonal Kunal that had this change. You can always solder it directly to pins of the drivers. It might make it sound smoother or help ensure stability.
