TUBE 6528

GENERAL DESCRIPTION


picture 6528 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.
