| TDP TUBE 6528 |
| GENERAL DESCRIPTION |
|
|
The 6528 is a long life, mechanically rugged, twin power triode developed especially for use as passing tube in series regulated power supplies. For this service, a tube must be able to pass large currents over a wide voltage range and still exhibit a low intrinsic voltage drop when operated "wide open". The 6528 adequately meets theser requirements. |
