Allow me to elaborate.

I have an RM-35M.  It has been in continuous repeater service for 
more than 10 years without a hiccup.

Recently our hosts did some electrical work in the building.  They 
installed new elevator motors and emergency power.  We are now 
connected to the emergency power through a very large (~60lbs) ferro-
resonate transformer.

The elevator motors and controllers are not in the same room as the 
repeater, but the main power passes through our room.  The repeater 
has been in the same location without any problems from the elevators 
for 30-years.  

After the change the RM-35M started crowbaring once or twice per day.

I replaced the power supply with another RM-35M.  It has been running 
fine for a couple of weeks now.

The original power supply, plugged in on my workbench, with no load, 
will crowbar after running for 3 to 12 hours.

So, will someone tell me about this replacement regulator board of 
Skipp's?
