Hi Sam
In that case I used a recycled red 100pf tubular ceramic. In the case of the 300pf cap for C1 which appears to be a tone corrector I used a 220 pf 630v tiny polyester PCB type with extra wire fitted to the short leads.
I dont have a very good selection of small value caps, other than a bunch of large NOS RS flat mica caps which dont fit at all well in a tubular case.
At the moment I am waiting for some green paint on a 200 ohm dogbone (which measures 260 ohm) to dry, so I can use it in place of the 250 ohm dogbone that someone has fitted for R5. (the one in the chassis measured 400 ohms)
Here is the circuit diagram of the KB 444 which is the same as the KB 346, which in turn is the same as the KB 402, and the STC 40. Or so my documentation tells me. Mentioned towards the end of this document. http://www.kbmuseum.org.uk/documents/KB_...models.pdf
