It's interesting to read your progress here Mike as it's similar to things which I do quite a bit of. I cannot say I have attempted to make a double tuned IF transformer, but it is useful to read. I know the issues with capacitive loading of a scope probe well. When possible I prefer to use a pickup loop but obviously the radiated signal has to be good for that. Not what one strives for with an IF coil.
It's interesting you mention Beam tubes. I recently had a little look at them for mixer use but, although the TV ones are around, it would be a bit of a diversion and obviously more common from the States with their high postal charges.
I look forward to your continued progress.
