Twin triode, the European version of the
12AT7, especially designed for VHF, also
good to use in audio amplifiers; high
amplification, low internal resistance.
Predecessors for VHF in Europe were the
pentodes EF42 and EF80. Successors were
the twin triodes ECC85, PCC85 and UCC85
with a special shield between the triode
units.
