Marconi KT2

Marconi KT2 2 volt 'kinkless' low frequency amplifying tetrode

KT2 pentode

This is an early beam or 'kinkless' tetrode and replaced the earlier PT2 pentode. PDF data sheets from the Osram 1938-39 data book are here and here. Data are given for operating two valves in quiescent push-pull. Valves were marked with one of three grade letters on the top of the bulb - V, W and X. These should be matched for QPP operation.
