Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Without Interstage Cathode Follower (Direct Coupling) | 250V | - | 63000 | - | 1.3mA |
| With Interstage Cathode Follower | 250V | - | 47000 | - | 1.6mA |
| Table II Case 1 | 300V | - | 63000 | - | 1.6mA |
Application Notes
The tube directs electron beams to either a sum (a1) or carry (a2) collector based on combinations of zero and positive voltages applied to the three control electrodes (g1,1, g1,2, g1,3).
