Extras ▼

 

The Z622 is an indirectly heated HF pentode based on the M-OV Z62. The CV1192 was based on the Z62 as were the earlier names of Navy NR79 and Army ARP21.
The envelope is coated internally making the internal structure invisible. The base cap carries the Marconi MWT logo.
The inner coating extends all around the glass.
The screens and the tops of the grid supports.
Here the control grid can be seen to be wound on copper and has radiating fins at the top.
The classic envelope is 30 mm in diameter, and excluding the IO base pins is 73 mm tall.
Reference: Data-sheet. Type Z62 was first introduced in 1939.
