I recently went to an estate sale and got 3 vacuum tubes, (RCA 24LQ6/24JE6A, RCA Radiotron R-CC 5, and Sylvania 3GK5) A nice metal pump (in cardboard box), and a tube handbook that might have been a waste of money because it is just a replacement handbook. I was able to find the pinout of the large 24LQ6 tube, but I’m still searching for the others. I also got a box of wires at that sale, but I did not show it in this picture since I already sorted through them and decided what I wanted to keep. Everything I mentioned only cost me 6 US Dollars.
