"Pearly & Mike"
Anyone heard of Haltron tubes?
** Eeeyep.
Anybody knows the history of Haltron?
** Haltron are definitely "history".
Were they made by Brimar, Mullard?
** LOL.
Famous brand UK made valves were worth a lot more if NOT branded Haltron.
AFAIK, Haltron ( = Hall Electric Ltd ) imported crummy valves from
western Europe, mainly West Germany, an re-badged them.

Same sort of operation as other dodgy re-boxing operations like "Trigon"
and " Teonex".
The boxes were always labelled with "London England" or similar - because
that was were their warehouse was located.
Big Joke !
