I replaced the 50uF caps with 100uF ones and I replaced the 'substitute' valves with the ones that should be there - and the baby jumped into life! - on shortwave at least for now. There is still noise at no volume but much less than before.
I managed to squeeze the 100uF caps underneath so I can use the large can space on top for a proper heatsink for the dropper resistors. The dropper gets very hot very quickly so I didn't want to leave the set running for more than a few minutes at a time.
Getting there at last!
Cheers, John
