I bought these only a few weeks ago as 100/100 measuring New In original Box pair with the help of a reputable forum member from rare, genuine stock in Germany for 600 euros.
You are looking at the best available 6V6 tubes, the holy grail Bendix 5992s.
These are from the Sperry relabelled stock; they are the real deal. You can see where the Bendix logo was removed and relabelled.
They come in original boxes from 1955, truly unused.
No other 6V6 tube comes close to the technicalities and subtle natural warmth these offer. Endgame tubes in Cayin HA-3A for example.
These are near new, I only used them for a few weeks. They should last you a very long time.
Don't take the gamble and buy those battered, very used offerings with questionable measurements from eBay. These are the quality version.
There is one small flaw you can see on one of the tubes: a tiny crack at the top of the base. Unfortunately, this can happen on nearly 70-year-old bases, but it does not affect usage. The crack can be secured with appropriate glue, if you are worried. The tubes are 100% quiet and reliable.
Some extra info from online sources:
"This is a military/industrial version of the 6V6GT, is probably the best sounding 6V6 tube you will ever get your hands on and is rather rare. The US Air Force was supplied these as spares from the Sperry Gyroscope Co, and they have the 5992 number taken off, and the Sperry part number on the base. Bendix Red Bank was the ONLY manufacturer of this incredible tube. These have rugged brown micanol bases, heavy glass, a short boxy black plate structure, three mica spacers and dual top mounted D getters. The brown bases can vary in color from beige down to rich mahogany and sometimes have varying shading on the same base. This is probably the ultimate holy grail tube to have in the 6V6 world, but their scarcity today keeps them in a fairly obscure corner of that world. Clients tell me these blow away even the NOS RCA blackplate greyglass tubes! They are indeed awesome, and will never be made again. All of these tubes glow blue inside and have slightly longer warm-up time than the 6V6GT, this is normal. They are plug and play compatible with any 6V6 type tube. These are worth seeking out as they are built like a tank and may outlast both you and your amp!"
"The Bendix 5992 is similarly rated to a 6V6 electrically, hence the interchangeability, but overbuilt in the extreme to withstand much harsher mechanical & electrical operating conditions and stresses. Something like a model rocket to a Saturn V (they may have been used in Saturn V’s)."
