I peal back the braid til there is enough center conductor to run through, and out the tip.  Strip back the tip wire ~ 3/4", tin, insert all the way and out, bend over but NOT onto the "shaft", just enough to "hook" the end.  Heat the wire and tip together with a clean iron til the solder wicks into the hole and seals.

I then fanout and trim the shield evenly around the back tapered part, solder ~ 1/2 way around rotate everything and reflow the rest.
no blobby globbies, smooth flow, caution with heat, especially the center so you don't melt the center wires coating.
buy 5, by the 5th one you're a pro, use good wire, good solder, clean parts

This is how it was done in the '50s and '60s before all those fancy RCA plugs showed up. Look at the black wire. It was stripped about 1-1/4", tinned, wrapped tightly around the shell, then soldered. Do this before putting the white wire in the center to avoid melting the white insulation. Then strip the white wire about 3/4", tin, shove it up the center pin until it bottoms out. The end of the wire should poke out the end of the center pin. Solder, allowing the solder to wick down into the center pin. Trim the excess wire. If you want a nice pretty rounded end, reheat and put a shiny ball of solder on the end of, kinda like putting a shiny ball on the top of a turret.

Use the same procedure when working with shielded cable. Note... If you use Teflon RG-316 you don't have to worry about melting the center conductor.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Thanks for that,  I've never soldered those types before.  I'm waiting for my 5F6a parts and will be soldering 4 of those.

:laugh: those guys taught me in the '70s n being a poo boy that could solder, I made a few $s fixing broke wires, could get good $s for wiring up an ignition "hot wire" switch  :icon_biggrin:

I just ran across this pic while browsing through some old HeathKit manuals...

Yeah, there was a lot of good basic technique stuff in those HeathKit manuals. Here's another pic I wish everyone that ever wanted to solder something electronic could see...
