CV45

Sensibly equivalent to:
GTR120A S130P
    
Extras ▼

 

Unlike the normal cylindrical construction of a CV45 voltage stabiliser, this CV45 uses an open corner and two rods in its design.
The CV45 has a maximum current output of 75 mA. This is above the normal range and was, therefore, designed to supply a stabilised voltage directly rather than act as a reference in a stabiliser power supply with a series pass valve.
The striking voltage was 135 volts. Pin 4 is a priming anode to strike the discharge.
One face of the corner cathode with fixings to both micas.
The main anode is in the centre with the thinner rod the priming anode support further away from the cathode. Note the actual priming anode is the short rod seen on the right near the top mica.
The pinch showing how the main components are welded to the contacts fixed to the pinch.
The balloon envelope is 54 mm in diameter, and excluding the B4 base pins is 103 mm tall.
