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 could make a adaptor , small 7 pin to a 8 pin plug.

I have 3 tube testers but none with the 7 pin small socket .

I would trade one of these test plugs / sockets for a 7 pin small socket or adaptor. I have 2 of each size .

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?

My main tube tester is a eico 667 with a eico 615 adaptor.

Could not get it to work , but my Radio City Products tube tester works with
both sizes . Learn something new everyday.

So, Garry, is the socket in the main chassis of the Eico 667 or in the
adaptor? My Eico 666 has the dual socket. Strange.

The 615 adaptor has a 4 pin 5 pin 6 pin and a large 7 pin .

I have another adaptor around here somewhere . When I find it , I will check
it .

I found the other adaptor It has the dual 7 pin . Both are eico 615
adaptors

That is strange .

I will post pictures of both adaptors .

Looks like I am good to test

Thanks

Gee, Garry, that is REALLY strange that a test adaptor for a tube tester
came with only a large 7 pin socket. The second example is more 'normal'
with the dual 7 socket with pilot lamp test provision. I wonder what the
manual for the 615 shows. If any socket was fitted, I would have thought the
'small' 7 for testing receiver tubes [such as the 6A7] rather than the
'large' 7 that was for more 'commercial/industrial' types.
