diy IF transformers: first attempt.

Thanks Sam, I think that guys posts are what originally gave Dad his ideas to use those axial chokes for IFT's, it's noteworthy that he didn't bother screening his. I believe that he had also seen some similar ideas in one of the MJF projects books, sent to him by his friend Greg in MS USA, that had construction details for kits that MJF enterprises, (Starkville Mississippi) produce.

Dr Ed, I admire anyone who can do that kind of repair, its a little beyond me, best I managed so far is a relatively simple fault of a detached wire in an oscillator coil for a Murphy battery set. My aim with this project is to design a radio using readily available components like the little chokes. Ambition is also to design the front end of a radio to use up the world stocks of EF80's 

....I have plenty of IFs of various sizes if you need any to experiment with....

Thanks for the offer... I'll know where to come for some! I don't like to experiment with stuff that could be used for the repair of vintage equipment,  but would love to find a source of the likes of denco or wayrad components

Project....
I managed to make a (close fitting) copper screening can that I enclosed one of the prototype IFT's with to see the effect, it didn't seem to seriously alter the coupling, but did lower resonance by approximately 25kHz, next I'll try a round screening can to see if that is more tolerable with what ive already made....

Thanks,
Amie.
