Congrats Tom,

You gave yourself   a nice Christmas present by not having to send it out 
for service.  I'm a big fan of  Astron supplies and have 2 of them that have 
never given me a problem.  I tell people " buy an Astron and  in a few 
decades your widow will be selling it as part of your estate sale".

But of course  there can always be a problem and some people have had 
trouble with the transistors.  There are 4 of them on the back of the  35 
amp supply.  you can feel them  in the large gaps between the cooling fins. 
Don't know how easy it is to  trouble shoot this thing, but hopefully  it is 
something simple like a  bad connection between the  supply and rig.  Be 
sure the  connections are tight on the back of the supply and  if using 
something like a Rigrunner or other distribution   panel, be sure all 
connections are well seated and  that any crimp or solder connections are 
tight.

Have you made any recent changes  in the  wiring between rig and supply?
