Tube socket test adaptors are becoming very hard to find and I consider them a valuable part of my work bench test gear. These are used to check voltage & resistance of the circuit under the chassis without removal of same. They are also quite valuable to determine the voltages of your tube tester without disassembly.
The socket savers are used to save the wear of the sockets of your tube tester.
I have posted all my extras and some I
won't be using for sale on my web site. Inquire to find out what's available.
