Up for grabs here is a very rare pair of 12AX7 new Old stock tubes both in the original boxes. I believe both of these tubes are TUNG – SOL rebrand tubes. This is a blue printing pair of tubes. One of the tubes has smooth black plates and an angled square getter. I tested it and it tested well with the new Old stock values. It was at like 990 on both lines, whereas a typical new Old stock tube averages 1000 so it is well within the average ranges. The other Tube has grey plates and a goal post getter with a foil strip with twin dimples in the foil strip at the tip. This tube also tested new old stock at 990 on both lines. I did a bit of research on these tubes and I believe they’re both manufactured by TUNG – SOL. Feel free to ask any questions you have order to make an offer. Thank you for looking. Have a blessed day.
