The 20 pot has two sections: one is the Antenna attenuator, the other is the cathode bias one.

To clear things up a bit. The Philco pot (33-5040) is single gang 3 terminals with AC switch. The picture shows how my pot is wired and the description of the post from the Philco parts catalog. Note the 32K resistor on my drawing is not on the early or late schematic. Looks to me like someone has wired the pot trying to use both the early and late schematic.

Oops, sorry. I've answered a question no one asked.

That's OK, Morzh, I do that all the time. If we could catalogue the answers to questions that no one asked, when they do ask them, the answer is there. It would be like we're clairvoyant!

[morzh]

Well, now you ask that question and there we are, the time travellers.
