Protecting GE Transistors Legs from shorting

Hey guys, quick question.  I usually dont have a problem getting these russian GE transistors into PCB's without risk of shorting the legs, but these old vintage transistors i've just bought have a really inconvenient pinout. i have to bend two of the legs in a crisscross fashion, and the transistor ends up looking, kind of like its in the middle of a game of Twister.

So the question is, can you put something around the legs, just for some adding protection against shorting?  only things i can think of are:
- heatshrink (heat might damage the transistor?)
- tape (mostly going to unravel though).
- Hot glue (Difficult to remove from the socket though)

Any other ideas? Thanks for any help!

Small heatshrink. Don't shrink it.

Or peel some insulation from hook-up wire, use the insulation.

Traditional product is "spaghetti", cloth sleeve for bare wire; but I have not seen that sold in decades.

You can still get non-shrinking teflon sleeving which should simplify things.  It is not affected much by soldering heat.

I just use the insulation from hook up wire too, I build a lot on vero, so need the copper for jumpers, so minimum waste.

These are my patriotic covers  ;D

maybe I've been lucky, but I've never had a problem with shrinking the heatshrink on ge's. though, I do cover the metal case and try to point the gun at the legs only when shrinking.

also, I scrap tons of vintage electronics and routinely pull what seems like shrunken heatshrink off legs....or was it just some really tight insulation...
always think outside the box

reminds me of the old bc10x fuzz face board. adapt the transistor to the board, no the board to the transistor. they kept that layout running for.. ahmm...

I've done both of these methods. Works just fine.
