CV5281 double triode
 |
This valve measures 54x19mm overall and has a B9A base |
This is a high-slope double triode designed for use in VHF cascode amplifiers. Triode 1 is normally operated as a grounded grid stage as a low noise input amplifier. The shield connected to the grid of triode 2 keeps coupling between the two units to a minimum.
