[Amps] choke resonances

[dan hearn]

I saw an article one time where a guy moved a RFC resonance in a pre
warc Alpha by making a single shorted turn of insulated wire on the coil
form.It was slid along the form until the resonance was in the desired
spot. You could use teflon spagetti  on a piece of buss wire. 73, Dan,
