The old ways > are not necessarely the best ways :-) Every CT I've built has had the resistor as close to the transformer (i.e., on it) as possible. I've had quite awful results putting the resistor on any kind of length. Come to think of it, that may be more due to the resistor itself having length, which would be a problem. Still, better safe than sorry... 'Course, I wind my own, encapsulated in masking tape, so embedding a burden resistor is no big deal. ;o) Tim -- Deep Friar: a very philosophical monk.
