KK32

 
    
Extras ▼

 

The KK32 is an octode frequency changer on an IO base. The same valve on the older B7 base is designated FC2A and was introduced in 1937. Philips also produced the KK2, in 1935, that was electrically identical but on the Ct8 base.
The triode details given refer to the triode oscillator formed between the cathode and grid 2 of the octode. The second grid was probably little more than two vertical support rods.
The classic envelope is 45 mm in diameter, and excluding the IO base pins is 109 mm tall.
Reference: 1043. Type KK32 was first introduced in 1946.
