Simple Jfet buffer R1 & R2

[Ctrl4Smilerz]

Happy holidays all!

I'm putting together my simple jfet buffer and I ordered 2M2 1/8 W resistors for R1 and R2 based on the build doc but the PCB has 2M printed on it. I know the answer is usually go with what is printed on the board but I thought maybe 2M2 wouldn't fit on board. So can I use the 2M2 resistors or should I get 2Ms?

The schematic says 2M also. It’s just a buffer though. Use what you have. It looks like they’re being used as a voltage divider, so you should be fine. The output, according to my calculations, should be the same.

Wow you're right! The schematic and screen both say 2M but parts list says 2M2. I should have caught that but sounds like it went matter much.

There’s a great app called ee tooolkit that’s really handy for things like this. I use it a fair amount.

Thanks, I’ll take a look at that. I was thinking I could also use Gemini to verify the part list against the schematic and a picture of the board.
