Extras ▼

 

The QQV07-50 from Mullard is transmitting double beam tetrode that was introduced in 1961. Primarily designed for push pull amplification in the VHF frequency range at powers up to 100W. In class C service the peak cathode current was given as 585 mA, the maximum average current being 130 mA.
Cooling was by convection or forced air and the valve was designed for mounting in any attitude.
As with all of these European pattern double tetrodes the neutralisation capacitors are internal to the valve.
Compared to the QQV06-40A the anode has additional cooling fins for better radiation of the heat.
The wide glass tube envelope is 41 mm in diameter and, excluding the B7A base pins, is 72 mm tall.
Reference: Datasheet. Type QQV07-50 was first introduced in 1961.
