Bob -

VR tubes have their regulation voltage as the number.  VR-105 is a 105 VDC regulator, etc., also 
known as an '0C3'.

VR-90 - 0B3

VR-150 - 0D3

There may be others, but that's all I can recall.  All are octal bases.  They are listed in the RCA 
Transmitting tube manual, TT3, but I can't find mine at the moment.
