Thanks Mike.

I'm just having a bit of a problem with visualising the transformer fed cathode circuit.

I have seen demonstrated a homebrew twin tuned trf where all valves were EF50's, 1 RF amplifier 1 II detector, and 1 audio amplifier, feeding phones. Pointless or not it worked well. But of course not rod pentodes!

Thanks.
Amie.
