Especially crowded areas like tube lug component leads (e.g., resistors)
Switch lugs…
Lamp holder lugs…
Unused/unneeded transformer wires…
Polyolefin
Pay attention to and leverage the different ratios (2:1 or 3:1)
Logistics:
Place the heat shrink “before” connecting (soldering)
Ensure it’s as far away as possible from soldering before shrunk.
Use a heat SINK if possible to draw heat away from the tubing (although I found with the proper soldering technique and simply paying attention, not necessary).
