832 / VT118 double beam tetrode
|
This valve measures 85x55mm overall and has a 7 pin base |
| Heater voltage | 12.6V / 6.3V |
| Heater current | 800mA / 1.6A |
| Max anode voltage | 500V |
| Max screen voltage | 250V |
| Max anode dissipation (total for both units) | 15W |
| Max screen dissipation (total for both units) | 3.5W |
| Mutual conductance (Va=250;Vg2=135;Vg1=-10;Ia=30mA) | 3.0mA/V |
| Max operating frequency | 200MHz |
| Capacitances |
| Ca-all (each unit) | 3.8pF |
| Cg1-all (each unit) | 8.6pF |
| Ca-g max (each unit) | 0.05pF |
| Cscreen-c | 60.0pF |
Note the two halves of the heater can be connected in parallel to run at 6.3V/1.6A
In operation a bypass capacitor needs to be connected between the screen grid pin and the cathode
and should be below the internal screen
