Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Capacitor Input Filter | 350V | - | 130 | - | 125mA |
| Choke Input Filter | 500V | - | - | - | 125mA |
Application Notes
The GL-6087 incorporates a unipotential cathode internally connected to the filament. Heating time is approximately the same as other heater-cathode tubes, minimizing surge voltages across filter capacitors. It is a replacement for the 5Y3-GT within rating limits.
