I recently built an extender for loctal tubes so I could access points with my scope and meter. I had to use an old faulty tube as the plug-in for the socket/tube under test. I purchased a nice socket base mounted to a pc board with access (numbered) terminal strips. It worked good for a while until I lost solder connections under my epoxied base.
Now I have to rebuild it again. Has anyone seen a prebuilt loctal extender (breakout box) for sale? I have been unable to find any male B8G plugs, that is why I sacrificed an old tube. I also bought a handful of 8-pin loctal bases (ceramic) and the quality is absolutely garbage (you get what you pay for). The pins do not have a good latch on them so they want to pull out with tube removal. Fortunately, I tested it before going through the trouble of blindly using them as replacements. Does anyone have any links where I can buy these items, otherwise I have to cut off another tube with my dremel and go through that tough soldering exercise.
