CBS JAN-CHY-6V6GTY tNOS AT1000 TESTED Vacuum Tube military brown base Premium Beam Power 1946-1960

This listing is for one (1) CBS-made JAN-CHY-6V6GTY Premium Beam Power vacuum tube in the straight-walled glass tube shape. It has a brown micanol or black bakelite base, black plate, and bottom square getter. Some of our stock is re-labeled or marked with the OEM of Hytron. If you're looking for a particular brand, please message right as you order - we pack and ship quickly!

Singles only. One early black base available: please inquire.

Your tube has been fully tested on a computer-regulated, USA-made Amplitrex AT1000 on Fixed Bias setting with like new, NOS results (tNOS). Here's what that means: to qualify for this listing, several stringent conditions must be met by the power tube: The plate current must measure between 36 mA and 54 mA AND transconductance must measure between 3280 uMhos and 4920 uMhos, consistent with original 1946 RCA, Western Electric, Sylvania, GE, and/or Tung-Sol datasheet specifications for new tubes of this type. The tube must also show no shorts, show a gas current less than 4.5 mA, and a heater-to-cathode leakage of less than 10 microamps (10 uA). The tube might have mechanical wear or have the label rubbed off - these are very old! Used-testing tubes are available in a separate listing at a significant discount. Every tNOS or Used Good tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!

These photos are not stock photos. You are looking at the actual tube you will receive. If a box or boxes are in the photos, you will get them. If test results appear in the photos, look close, because those are the test results of the tube you will receive! SKU 6V6-210m. Please note that matching is nearly always possible for us from stock that is inventoried but not yet listed. If you need a matched pair or quad etc., please use the make-an-offer feature through Reverb. Matching requires an extra burst of effort, so please add $5 per tube to your offer for 10% matching and $10 per tube for 4% matching. [Matching is based on plate current for power tubes, voltage drop for rectifiers, and GM for all other tubes. If you also require the label or internals to match, please specify that in your offer.]
