National el84

[Buschman]

I've got some National branded el84,says made in Yugoslavia. Other letters on the tubes are km4 & ABC. Any ideas of the manufacturer?

Might could tell if you post some good pics. Possibly EI's.

Ei's. The early ones are great tubes, just as good as Mullards. The last run of the original so -called old ones were also Sylvania labeled, they were the Holland EL-84 / 6BQ5's, dark gray plates. Don't see very many around anymore. These were being produced while the breaking up of the Philips Co. was happening. But you have to look close at the getter and port to see if they were the old style. Welcome Back !!!! " Rock N Roll Is Bigger Than All Of Us "
