The RBL is an excellent receiver, as good as the RAK, and has the 
advantage of a calibrated dial.  Mine was never in service, and all the 
mica capacitors were shorted or arcing.  The power supply is internal .  
A good find.

The RAK/RAL power supply has a design defect in that some voltage 
dropping resistors are nestled underneath a fiber board with no air 
circulation, and are always shot.  Also they put too much current 
through the 884 regulator as it's only regulating a half-mill load.  
It's easy to make a power supply - I've gone both ways, and it may have 
been less work to make a new one.
