Hi ed and everyone, the frame coils are fixed and not moveable, I have decided on a design and have put a wanted ad in for chokes and LF transformers. A couple of questions if I may, 2 variable tuning condensers are specified and are .0003 and .0005, now I have the original one from the wreck and a spare one, there are no values marked what so ever and I would guess that they are many times too big, so is it possible to measure them and how please, I have asked for chokes but if they should prove difficult to get would a coil wound on a resistor be OK? Also the transformers is there an alternative ? Modified sound or mains Tx? Just scrambling around as I dont know just how difficult these things are to get.
Thank you.
Cheers.
Geoff.
