PL519

 
    
Extras ▼

 

The PL519 was a line output valve, or sweep tube as they were known in America. This example is of late manufacture and probably the last to be produced before transistors took over the role. They would be found in large screen colour televisions with an EHT of around 25 kV and thus requiring considerable line drive power.
The parameters given are taken from the data-sheet and refer to pulse operation.
The wide glass tube envelope is 36 mm in diameter and, excluding the B9D base pins, is 112 mm tall.
Reference: Data-sheet. Type PL519 was first introduced in 1970. See also 1970 adverts.
