Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Rectifier operation at 250V input | 250 V | — | 125 | — | 180 mA |
| Rectifier operation at 127V input | 127 V | — | — | — | 180 mA |
Application Notes
When two valves are placed in parallel, Cfilt = max 100 uF. The resistor Rt must be inserted in the anode lead of each valve. Max heater-to-cathode voltage consists of max 220V eff AC + max 250V DC.
