This is a set for 7/8/9-pin tubes. The test points aren't as exposed as some other types with tabs sticking out. Ouch sometimes if you forget. I got nothing to do with auction. Other ones currently listed on Ebay. You might want to search the for sale ads on the other radio type sites. Search web.

:I'm looking for 9-pin(12ax7) and 8-pin(6L6) tube socket extensions with exposed terminals to measure individual pins. I've seen them many years ago but require one apiece now. Any help would be greatly appreciated. Thanks...Mark
