(1) A tube extractor enables you to remove electron tubes from their sockets. It is a great help in
pulling out tubes that are still hot or that are in hard-to-get-at locations where you cannot
grasp and pull out the tubes with your fingers. The dark portion of the extractor is a rather
soft, nonslippery plastic coating to allow a good grip on the glass sides of a tube.
(2) The pin straightener consists of a die on either end. One end is for seven-pin tubes, the other
for nine-pin tubes. You operate the tool by simply pushing the pins portion of the tube into
the appropriate die which resembles a tube socket. This action straightens any bent pins the
tube may have. You then remove the tube from the die of the straightener, and put the tube
back in its regular socket or return it to wherever a supply of good tubes may be kept. Most
tube straighteners are of aluminum carefully machined as a precision tool.

(1) Contact burnisher. Dirty contact points in relays and in other circuit components may cause
electrical and electronic equipment to malfunction. Then is when the burnisher (item A) can
help you rub contact points until they are shiny and clean, and able to seat against one another
properly for a good electrical connection. The burnisher comes apart like a fountain pen.
