Extras ▼

 

The PCF808 triode pentode offers high voltage gain in a screened design. It was probably designed for VHF television use.
The Mazda 30FL14 is a direct equivalent.
This exhibit is distinguished by the blue lettering and the fact that the pentode anode is visible. In the Mazda PCF808 and Solus PCF808 the screen encloses the pentode anode.
The anode of the pentode section.
On the left is the triode.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 48 mm tall.
Reference: 1040.
