Price is for one tube, if you buy two then I will ship a pair, matched in the box.
New condition, boxed. Shipping from Washington, DC area in the U.S.
SG 845B is a modern replica of Philips 845 tube of 100W dissipation power and further developed by using carbon plate material. Thus it could working under very harsh high plate voltage and high current required for commercial amps when other designs of 845 tubes would not last long.
I got several pairs in new condition, boxed with matching, I further tested them to make sure working condition before shipping out.
The price is very reasonable for what it is. Currently there is no production of this tube.
Buyer should act before too late.
