Sylvania 6SN7gtb Chrometop ,organ grade with matching date and production codes

These are organ grade tubes, screened at the factory for being extra quiet. They also share matching 1959 date and production codes, very rare indeed. Great opportunity to own fantastic sounding tubes. Very nice sonic signature, with wonderful balance and control no matter what you throw at them. This tube has developed quite the cult following. Great preamp tubes, though many people love them as bulletproof driver tubes in amps as well. For price to performance ratio, these are an absolute no brainer. Price is per pair. Get them in this condition, with these matching codes while you still can, pairs will be matched. All conditions firm, ships from Canada . Tracked expedited shipping flat $17

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
