The VR100 is an M-OV Type KTW62 supplied during WWII for RAF use and later re-named the CV1100. It is a vari-mu IF kinkless tetrode of the 6K7 class but with slightly more gain. Thousands were supplied during the WWII with the KTW62 used in the CR100.
The classic envelope is 36 mm in diameter and, excluding the IO base pins, is 102 mm tall.
