Hi –

I used to use heat, small flame, and then scrape off the residue. Then you can wrap fine wire around the clear Litz bunch and connect the other end to the lug. The wrapped wire should be solderable. I fixed several BC611s with the same problem. 73 – Mike

Subject: [Milsurplus] Litz wire question

Hell all,

Working on a receiver (R-114/VRC-4). I was having some issues with the IF, so pulled one of the cans out to inspect.

And found that one of the Litz wire leads had broken where it soldered to the terminal lug. There is about a 1/2" loose flying lead out of the coil, and continuity to the other end.

What would be the best way to strip the end of this flying lead, without stressing it too much. I'm afraid of breaking the lead where it comes out of the bottom of the coil.

Found out that one other coil in another IF can has the same issue.

Funny thing was, the receiver actually was functional, although the gain was a bit low, and the IF was broader than a barn. The DC paths to the tubes were provided by the swamping resistors.

Thanks
