One pair (2) 6K8G from WWII production.
Tubes are most likely made by GEC. All tubes carry the old British military designation ZA5307 which was used before and during WWII for this kind of tubes.
These came to me in military bulk box, so the pair comes without boxes but will be packed carefully.
We will test each and every tube before shipping to make sure that you will receive fully working examples. All tubes we tested so far test with 100%+ on the triode section.
We will be happy to match pairs as long as our stock allows for it.
We do have more 6K8G also from other brands. Should you need a matched pair, just let me know.These tubes are guaranteed to be new and unused from former military stock!
