6550 SED "Winged C" matched set 16 tubes

SOLD



Selling quads. One set remaining
$375 plus shipping

NOS Never used other than testing and burn in by vendor. I bought 5 years ago and sold my amps.
If you are looking you know these are rare and some say the best 6550 tubes ever made and will never be made again in all likelihood. They are Russian Svetlana not those TAD or any relabeled newer production.
Most are dated around 0144 so later 2001
