(I'm not familiar with that part - my SP-600's all have line cords going in
through grommets as far as I know.) Please replace what's there with a
three wire grounded line cord.. AND: move the tap on the power transformer
to the higher voltage tap. (The SP-600 is unusual in that it has this.)

No problem. Just get an R-390 and use a crystal controlled converter down
to 7 or 14 mc.

Normally they were two-conductor, SO-239-like connectors for twin coaxial
cable. Many of them have been changed to SO-239's or BNC's.
