[QUOTE="jeallen01, post: 1057888, member: 176704"] Now back again! Unwrapping txfr windings is often quite difficult because they are usually, or should be, resin/varnish impregnated - sometimes it is better to section the transformer with a fine-toothed saw to show the cross-section of the windings and core. Even then, and especially on a very small Txfr, you won't be easily able to see how many insulation wraps there are, and/or whether they extend sufficiently past the edges of the winding wires. Anyway, the main issue ATM is the EMI - and that looks like a slam-dunk "failure" for constructional reasons. [/QUOTE]
