Our specimen of QV04-7 is incorrectly labelled by the previous owner. The actual designation was a CV number but this can not be read.
This single beam tetrode looks like an early all glass envelope design. The output is modest and the dissipation high in relation to the output. This suggests use as a frequency multiplier rather than a class C power amplifier. Alternatively the design was just not efficient.
The wide glass tube envelope is 32 mm in diameter and, excluding the B9G base pins, is 58 mm tall.
