Unless you trust cover to sinks makeshift insulation which I would be doubtful about in the long run. Prone to mishaps.
Will glow nicely through that. If there will be air con in the room better improvise something to block the input FETs from drafts or unpredictably high ambient delta. It will be cooler with the perf cover but also exposed. Use the mini sinks if you got them or make a mini matchbox to enclose them.
"Another useful tip is before pushing the optional mini sinks on the input JFET(s) prepare them collars a bit wider with the pliers and form fit them on another same case transistor or Jfet first. Else the pressure will be too much for already soldered Q1 Q2. "
Jupp, I had a hassle getting them on top of the JFET's. God luck that I assebmled them before soldering which included widening. I had to get the legs in place after the procedure...

Hi Salas,
Can't find R13 -> Vishay CCF02 2.2k 2W. Mouser is out of CCF or CPF for that value. Partsconn has Kiwame 2W 2k2, but it is Carbon Film and no PPM data.
Is it an issue to mix PRPs PR9372 and Vishays MRS25 (both metal films) with Kiwame for synergy perspective?
I used Kiwame in my Tube projects and can't say any bad word about these.
What about JFETs cirquets and Kiwame?

Can you please share with your Raw PSU schematic and parts brands.
I see you deviated from Salas original setup.
Also, I see that one of your channels (left channel in picture) has 2 C2Y caps and other (right in picture) has only one. Is that related to certain channel matching?
Thank you.
The caps was to get exactly the same value in both channels. I have not tested my supply. It is not finnished.
I think you shall follow Salas power supply.

Mouser Part No:
71-CPF2-J-2.2K
100ppm 5% buy 4 to find the two nearer ones and install.
Mixing is no problem, still Kiwame has a "tone" not neutral.
I, being a Scotsman, interpret plate to mean a thick sheet.
eg. a steel plate is a thick sheet of steel.
I ordered today:
71-CPF22K2000FKE14
MFG Part No:CPF22K2000FKE14
CPF22K2000FKE14
Vishay Metal Film Resistors - Through Hole
US HTS:8533210090 ECCN:EAR99 COO:US
It just got back to stock in Mouser and it is 1%.
Thank you.
