Equivalent circuit for a split 2Meg pot
#3

Audio taper!  Bummer, I got a pair of linears.  I am doing this project to learn about tube radios, and the most effective way to learn is to make mistakes, so I'm learning a lot.  I will get in touch with Mark.

In the meantime I went back and looked at my history to find the circuit.  It was described in the UK Vintage Radio site.  The link to the circuit is  here.  The circuit uses two coupled 1M pots, and provides a pretty nice Bass boost at low volume. And, of course, it uses log pots.  I'll pursue this and let you know how the 38-7 likes it.
