Hi,

Do you have to use the 2N3904 instead of the TO-18 if you have 8580 R5's?

Thanks

As far as I can see it's:

VR1, VR2 220K
VR3, VR4 (trimmers) 250K Sub-mini
R1, R2 ?K2
C1, C2 4700pF

What are R1 and R2?

and have I got the others correct? The image is tiny!

This is the clearest I can find:

Thanks

Thanks. I have read through but the values are not present and seem to conflict with what I can make out from the best version of this image I can find.

There’s one in google images but the values aren’t clear.

The maplin codes don’t exist anymore and they replied to me saying they no longer stock those parts.

Sorry to bump an old post...

Is this the diagram in the OP's post?

Does anyone have a clear image of the diagram and a correct list of components (including values)?

Thank you
