Make this "Lead Twister".
This is used to create little curls or spring like loops on the ends of new parts (resistors, capacitors). Once there are little spring like loops on the end of the new part it is easy to slip it over the cut ends of the old part.
The parts needed to make up the Lead Twister are:
1) An X-acto knife handle or dollar store equivalent.
2) Epoxy putty stick found at home building stores plumbing department like Home Depot or Lowe's.
3) Medium sized safety pin.
4) Strong wire cutters to cut the safety pin.
The alternative to twisted leads are little hooks.
Cut the the leads of the old part at the body of the part. Form two little hooks on the old leads. Form opposing hooks on the new part. Engage the hooks, crimp them closed and solder.
"Well", you say, "Paul, why don't you unsolder the part at the solder tab of the tube socket? Besides it is the right way and better looking to totally replace the part!" I used to do that until I broke a few tube sockets and brittle terminal strips. It is very frustrating to acquire and replace a matching tube socket in a vintage radio. I replaced a few in Zenith Transoceanic cramped chassis radios. This "snip and replace" technique keeps the new part centered, in the position where the factory placed it (as in the aforementioned Transoceanic). You never know when a components position is critical or not. You do not want to go through al the work of replacing parts and come to find you induce hum in an amp, created cross-talk/feedback or detuned a critical RF, IF or oscillator circuit. And, I don't mind saying, this way (or the hook method) is much, much quicker.
I use this technique on PC board too. Try and not lifting a copper trace off of the PC card while removing an original part, causing damage. It is hard for me not to. So I clip out the part, stand the led wire perpendicular to the PC board, slip the twisted lead wire over the old leads and solder. I have not lifted a trace yet using this method.
This Lead Twister may be the primary tool that I use for all restorations.
