Vacuum Amp Tubes Bundle KT66 6L6 12AT7 34LS 12AX7WA Groove Tubes Sovtek RCA Ruby

In the first photograph, the tubes on the left side are all "new old stock."  They've never been used, but have been in our inventory for a while.  Tubes on the right side are "used."  We used a tube amp tester on all tubes and they tested "good." Photos of the NOS tubes are in the beginning followed by photos of the used tubes at the end. PLEASE NOTE: Sometimes tubes will test good in a tube amp tester and present an issue once they've been in use.  For this reason, these tubes are being sold "as is" with the understanding that some may not work properly or all of them may work just fine. **They are extremely discounted for this reason - valued at $700** Included in this bundle are the following: NEW OLD STOCK TUBES: Groove Tubes KT66 Duet - Matched Rating 5 - Quantity 1 Groove Tubes KT66 Duet - Matched Rating 7 - Quantity 2  Groove Tubes E34LS Quartet - Matched Rating 4 - Quantity 2  Groove Tubes 12AT7A preamp tubes - Quantity 2 Groove Tubes 12AT7 preamp tubes - Quantity 2 Ruby 6L6G
