RARE 1959 Vintage Medical-Grade Amperex 12AX7 / ECC803 Preamp Tube - Balanced & STRONG - MUST SEE!

Had this pair up, but someone purchased one recently, just relisting the one that's left, still the same great tube! Grab it quick!

This is a RARE, medical-grade, Nov 1959 (9K1), Herleen factory) Amperex 12AX7 /ECC803 tube. These medical grade tubes are very hard to come by, and to have a pair out of the same machine and near date codes is even harder. This particular tube came out of old hospital equipment, and that equipment was backup, from what I was told, so the tube saw very little use. Test results indicate the same (66/66 where 60=NOS level on Accurate Inst. Model 157 and 10/10 balanced on Orange VT-1000)

These were built to higher specifications and standards, due to the fact they were being used in high grade medical equipment and could not fail. These were tested and screened for VERY low microphonics & balanced triodes for true fidelity/accuracy in medical tests, as well as designed to have extremely long life (10,000 hours+), so these tubes won't have to be replaced for quite a long time.

This tube's tone is insane. This will set the tone for your amp in the V1 slot, and build your sound around it. Very lush, warm tone, even across the board, the tone you expect from a tube this serious. The price? I'm interested in making your tone AND budget happy.... =)

Don't sit on this, grab the tube that will change your tone NOW!

Discounts, offers and combined shipping are always available for multiple tube purchases.

If you have any questions about tubes, configurations, what subs work best, etc etc etc, please ask BEFORE purchase, I'm always glad to answer as many as you have to help you get the best tone out of these tubes!
