I want to put colored (red,black) heat shrink tubing on speaker cables that covers a portion of the terminal ends of the wire and part of the connector. This is both for aesthetics and to secure connectors. There are numerous types of tubing available depending on properties you want (tubing type,shrink ratio,wall thickness). Can you tell me what you have used? Also where is the best place to obtain this; I only need a relatively small amount and don't want to pay more S&H than the tubing cost itself. RS only carries bags with mixed sizes, most which I can't use. I live in No. VA area.
Thanx for your help.
