Mixed Lot Of 8 6AC7 Tubes RCA, Sylvania, US Navy CRC Untested Read

This is a lot of 8 untested 6AC7 tubes. They are all from different brands and are unmatched. Includes RCA, Sylvania, and US Navy.  These tubes were all from the same collection. It was a large collection of tubes, both boxed and unboxed, that we’ll be selling simultaneously via auction. The person who owned these tubes took care to separate by type and separated non working tubes, marking them with an “X”. These tubes were separated and were clean, but we can’t be sure that they work. Some of these are marked “Ok” which is a positive sign, but again, we have not tested them.  Selling as is, please bid accordingly and view the photos for any physical signals of condition.
