Eico 666 Tube Tester Data for 6922 and KT-90?

This link will take you to Tannenbaums web site, where there are dozens of tester charts and rolls available. I think they have a complete chart for your machine, which gives data for every available tube for less than $30.00.

The 6922 should test Similar to the 6dj8, there may be some minor varriations, I dont have my RCA Tube Manual in front of me right now, but they are interchangeable in audio circuits.
