A couple more questions...

[Jack Kovar KE0AX]

	Roy,

   I have a schematic of a RS-20m in front of me!
As regards to your GROUNDING question, the - terminal, transformer, 723 
regulator, and ac ground, and metal frame of supply are all tied together.
Most household grounds are considered less effective than a ground rod
eight feet in the ground with all of you equipment tied to it.
	INTERMITTIANT CURRENT SERVICE = ICS = SSB use =front pannel rating.

	CONSTANT CONTINUIOUS SERVICE = CCS = constant current load= less than

	ICS rateing.  

	EXAMPLE: 20amps ICS may be 16 amps CCS.

	Thats may story and I'm sticking to it!
