[ARC5] Homebrew choke

[J Mcvey]

for what? tx , rx , lv or hv?I needed a HV choke for the homebrew 12V dyno supply so I used the primary of a 12V filament transformer which had close to the correct inductance.Worked fine and held up to the 500V and 200 ma current. US house voltage is in excess of 340 vpp anyway, so I figured there was at least a 50% safety factor on the insulation...

 Anyone have experience or even just anecdotes about making a B+ choke?Interested to hear suggestions, no matter how weird the core you used.
