I don't remember the wire size I used (it's been over 20 years) but you're right about the short circuit. Just one shorted turn will form the shorted secondary of a transformer, and the I^2R losses in that turn will create quite a bit of heat that will further damage the insulation on the nearby windings until the whole thing is toast. _______________________________________________ Sent via AMSAT-BB@amsat.org.
