Default 7189 or 7819 el84 tube?

Dear all,



I need 7189 or 6bq5 for my Diy Amplifier but vendor quoted me a pair of Trigon 7819 and tell me they are 7189.Factory mistake only Labeled.
I see tubes structure .They are Pentode but cannot find datasheet for 7819 tube.

Is there any Vacuum Tube number 7819?
Thanks,

I doubt it so he might be right. In any case you now have a collectors item.

You mean a tube with faulty print is very valuable?? Like the Swedish stamp Three Shilling Banco that is printed on yellow paper instead of green?!

Slightly OT:
Going for Russian equivalents you'll end up with three types - 6P14P, 6P15P and 6P43P, where the latter is regarded as the bst for audio amplifiers.
