For your search.
The 150p also called "styroflex" or choose FKP2 like this:
FKP2D001501D00HSSD WIMA - Kondensator: Polypropylen | 150pF; 5mm; +-2,5%; 4,5x6x7,2mm; 1kV/μs; FKP2-150P/100 | TME - Elektronik Bauteile
FKP2D001501D00HSSD WIMA - Kondensator: Polypropylen | 150pF; 5mm; +-2,5%; 4,5x6x7,2mm; 1kV/μs; FKP2-150P/100 | TME - Elektronik Bauteile
That's what i use.
The 22p is also called "silver mica" or take a KERKO 500V disc capacitor.
Standard :: Silver Mica :: Capacitors :: Passive Components :: Electronic Parts :: Banzai Music GmbH
Mouser or Digi Key should also have stocked them.
Glimmer- und PTFE-Kondensatoren | Kondensatoren | DigiKey


To Mooly and interested it was #719

where prasi shared the schematic and layout with paralleled R9-680k to 22p.
 
Good luck 🙂 Have a look back at some of the designs that have been posted by Prasi and AlexMM.

There was one error on this one (arrowed) but otherwise it looked an easy to copy design.

Hello Mooly
greetings rough pcb for testing its prasi design

warm regards
Andrew

Andrew,
I havent looked at the layout in detail, but I suggest to keep the original feedback take off point as per my design. There is a specific reason for that to reduce THD.

Make an extra drill in the layout and use a wire to connect.

regards
Prasi

P.S., if you look at my design, its single sided only but with repeat traces on top. and feedback takeoff can be a wire. just 2c.

Yes sorry for that, but I have to admit I did not remember that post. I did read most of the 1000 posts but did not remember that you had been so kind to share your files. 🙂


Edit: it looks like it's the gerber files, or am I missing something?
I was looking for the project files🙂
