[Milsurplus] What is the difference between a RBM and RBSreceiver?

[George Babits]

I think the major difference between the RBS and the HF RBM is the mounting 
system and the dial lock on the RBS.  The power supplies are quite different 
though.  The RBM power unit is a conventional rectifier; the RBS is the 
rectifier plus an audio amplifier using a pair of 6V6 tubes.
