[R-390] IF out cable needed

[Barry]

The right-angle connectors are also repairable.  There is a disc soldered to the "side" of the connector that will pop out when the solder is melted.  Be careful, wear eye protection, etc., as hot solder can splatter easily with this operation.

Once the disc is out, the center conductor repair is pretty easy.  There are cut-away drawings of the various connectors in the manuals.

Barry - N4BUQ
