[TenTec] Rsc value for LM723 in 280/255 power supplies?

[Peter Bertini <radioconnection@gmail.com>]

Hello to the group

I'm in the processing of rescuing a much abused TenTec 280 power supply.
There is no amp meter on the front, but it has the speaker, so
I assume it may be a model 255 despite what the label shows.

The supply had major problems. Most the transistors were shorted, as well
as the
LM-723 regulator IC. The .62 ohm resistor (Rsc) was also vaporized. I'm
curious
what this part was used for?  I assume that 13.8/0.62    means that the
this resistor
set the maximum available current at 22 amps?  If so, is the adjustable
current pot
a second over current setting that works independently for setting a lower
max.
current output for this supply?

regards

Pete
