Looking for a tube adaptor to test a small 7 pin tube (6A7) in a large 7
pin socket or just a small 7 pin tube socket .

I understood that many [most] tube testers have a 'universal' 7 pin [large
pin] socket that will take both large and smaller pitch diameter tube bases.
I think that all my tube testers have them. What model tester are you using?
