If you have any dead octal tubes break them up and save the old socket pins in the base. It's easy to de-solder the wires in them to get a clean hollow pin. I've found a use for three already. I'm working on a Silvertone R1181 and the outside antenna wire was missing from the terminal on the back cover that connects it to the radio. It plugged into a socket on the chassis. One of those pins fit perfectly so I made up a new wire. The second use; I used them to make a removable power connection on a GE 511 clock radio. The AC cord goes directly to the clock and then to the radio. I made the wires going to the radio part so that I could unplug it from the clock without removing the clock also. I used the female socket for the pins from an old computer four pin connector. It worked out very well.
