The AC/G Cosmos (Metro Vick) is an early AC indirectly heated valve.

The valves released in 1927 were the AC/G and the AC/R output triode. We have already shown other pattern of these valves.

The valves have a modified base where pins 1 to 3 were as the B4 pattern and created to plug into a B4 valve-holder

All four valves have balloon shape and tested OK.
