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.

Eico HF-87 stereo amplifier that will require 4x EL34, 2x 6SN7GT and one 12AX7 tubes. No tubes or cage are included. This unit is stamped by Eico on the underside of the chassis so it leads one to believe this unit was factory built. I see capacitors and resistors were replaced sometime in the past and a surge protector was added. I used my spare tubes to test and it sounds great, no hum. This weighs 31 lbs.
