EAT's 300B is pretty cool looking, too bad they cost a fortune.

I believe this is a Tung Sol copy of the GEC TT21/22 (or the other way around, who knows)... and that is a KT88 derivative, by the way.
It apperars that your tube was made around 1968, does this sound about right?

I'm thinking this could be outsourcing and a rebranding issue maybe.
It migh also be that you tube has been made by GEC or something...

As for on sale, well.
I managed to track the TS-439B or A to an add from 1990... a chineese site.
So it appears that it is very rare indeed!
I used "ask jeeves" one of the oldest search engines, it gave me an exceedingly old google string, and then I looked for a
"design matching the description".
It appears that it was designed in 1968, a paper is filed on it april 4th 1968, but I would have to pay $24 to know if it is actually that tube, so I didn't...

this is all very shaky info, but I did find this now: by Bryan Lockey...

"Incidentally, my colleague Mike Forsyth and I "invented" the TT21 series transmitting valves which are based on the KT88 audio beam tetrode. We were ardent amateur radio geeks in those days, and the 807 was an icon, but low-ish in power. 150w was the governments limit. The 813 was far too big. The GEC equivalent 807 was the KT8C, a puny 1930's job. We realised the KT88's internal capacitances were quite low, and we persuaded the girls on the production line for the U19 rectifier (a top-cap anode job with a similar glass envelope) to put through 6 KT88s with a top-cap anode wire. It only "cost" us two nights each at Hammersmith Odeon, and as desirable 18yr. olds, was rather well worth it!). We approached the company station G3--- guys with these 6 for advice, and before we knew it, it was up, up and away. Thanks, Pat Cundy, and George Jessop.

Regards,

Bryan Lockey.

PS The KB/ numbering triggers vague memories. Z was GEC/MOV, any following letter denoted the factory--but there were only Brook Green and Wembley by 1958. D was for Mullard at Mitcham, and a similar regime followed. Certainly Blackburn was still operating in 1958, but other details have escaped me."

Maybe somebody at Tungsol did something similar with a 6550... eh?

good searching Imperial

hat off

This is a Svetlana KT88, Cryo'd I believe. (new production)

It's very symmetrical and I think it's a beauty to look at!
It's that SV / PL glass envelope shape.

This is a NOS version of the same tube: Note the difference.

Beautiful, but $2,750 per tube.

Oh yes, during handling of the tubes, I have to admit to a slight fear of letting this $2,750 tube statuette slip through my fingers and go crashing to the floor.

A Westinghouse mesh plate 227. I haven't gotten around to building an amp for it yet.

Emission Labs W520Bv2. These are modern 300B types but actually have a larger plate than the 845 type.

You can also see a new old stock Mullard GZ37 as the driver tube.
