And you don't have any NPN transistors around? With one you could buffer the output of your sig-gen to

Amazing.... Those are about the most common components around. I think I buy 2N3904s in lots of 1000, I use
so many of them

FWIW I do have Bristol spline keys here. Needs for working on IBM and Friden machines for a start.
FWIW, this is not the miltary or firearms list, so I wouldn't expect people to necessarily have the
equipment and spares for such things (if you do, fine). It is the classiccmp list, where some people, including
your good self restore the actual old machines. And yes, I think it is is reasonable to assume they will
have access to common (very common) electronic components.
