[Elecraft] OT - Astron RS-20A Issue

[Lee Buller]

Ladies and Gents....

I repaired an RS-20A recently.  The balancing resistors from the pass transistors had burned up because someone put a 15 amp fuse on the primary side with a load more that 16 to 20 amp on the 13.8 volt side.

Not ever done this before, I made sure the 723 was set at 13.8 volts and then used a 12 volt light as a load.  She regulated quite well.  

But now, the regulation voltage has increase to 15.5 volts.  This happened over a 24 hour period.  This does not seem right to me...and I wonder what some of you thing about this.

In our day and age it seems that Common Sense is in short supply.  If you don't have any Common Sense - get some Common Sense and use it.  If you can't find any Common Sense, ask for help from somebody who has some Common Sense.  Is Common Sense divine?
