Taylor Model 60 signal generator

[Sinewave]

I must add that the triode pin 1 goes to is the audio triode.

I've just taken the RF stage apart to see - Mod Tx 6 is going to the RF tridoe anode.

Whilst trying to fathom this out, I wonder if this is a rare item as there's nothing on the internet about the model 60.

Following the drawings for the 65 isn't much help as it appears to have a different modulation transformer.
