A Simple, Valve Curve Plotter

[SurreyNick]

Thanks for the article Lawrence. In fact I have a copy of the Handbook but until now it is unread. I have been referring to the subject in one of my FJ Camm books until now but the chapter you provided is much more comprehensive so I'll study it and expand my knowledge further. I will also do as you suggest guys and will use wire wound higher value pots. I will also use a DPST switch.

If I wanted to test pentodes too, perhaps switching from one circuit to another, do you know of a source of information from which I could derive a simple circuit?

Thanks

Nick
