[Hunts smoothing bomb]

Hello guys (and gals)

The tuning coil is mass produced, don't ask me where to get this type though because last year I took shed load of NOS components from a friend of mine who aquired them from the science department of a school.
The coil has one centre tap which I havn't used. I had to wind my own reaction winding though this was done by laying the windings straight on top of the tuning coil.
I have built one of these circuits before and what I used then was 65 turns of thin enamelled copper wire on a toilet roll tube with a paper sleeve around it, tight enough so it would just slide up and down. I then wound 25 turns of the same wire on the sleeve. after connecting it all up you can slide the sleeve up and down untill you get the best reception and then seal it with glue. I had very good results indeed with this type of coil.
I will post a circuit diagram of the set I have built tomorrow so if anyone wants to build it and give feedback on how it can be improved then they can...

Buy for now
