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

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.

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.
