I now know the Send switch is up for receive. Strangely, it only receives when the BFO is on but given the original condition I am expecting problems including shorted vanes on the trimmers.

I tested the valves and have one weak 6BA6 (I put that in the BFO and that is whistling merrily) and more seriously an ECH42 with some grid leak for which I don't have a spare.

Before I can do much more I need to sort the high HT out and have found a 24V transformer that I will wire as a bucking transformer to reduce the AC by 10%.
