RCA 12ax7 long plate angled square getter, Circa 1950's, organ grade same production codes

Available here are 5 pairs of these top tier tubes from the 1950's. These have the same date and production codes, organ grade from the factory, chosen because they are more quiet, which for us audiophiles means a blacker background/ lower noise floor. Rca tubes really excel at 3d imaging. In this condition, get them while you can as vintage tubes remain the most economical improvement you can make to your system. They all test at or close to new, price is per pair, PayPal add 4%, all conditions firm. $10 regular Airmail, $20 4 day tracked shipping

All tubes are tested on 2 different and very accurate mutual conductance testers with no bloated or just plain made up results, with tubes especially, do not lose sight of the fact that most often, you get what you pay for. Tubes will be packed tightly and safely; look to my other classifieds for other fine vintage tubes, and be sure to drop me an email with any questions, or inventory needs, thanks
