Thanks to all of the kind replies.  A little research has helped me figure
out what is going on.  If you try to track down the caps with screw
terminals (like came in the amp) they are VERY expensive, even from Mouser
or Digikey.

I have decided to take the project on myself (eventually) and use the much
cheaper 'snap in' style caps.  It will be a while before I even start, but I
will keep the group posted.

Thanks Again and 73,

A little over a year ago I acquired a working Ten Tec Titan 425.  It spent a
year in the closet as I had nothing to load it into.  I finally got the new
antenna up and turned on the amplifier.  After about 30 minutes the fuses
popped and the amp was dead.

I took it to Burghardt Radio Repair and Jim said the transformer was good,
but most of the rest of the supply was toast.  I believe him as he has
always been fair and square with me.

He said there was a mod that added another diode to each leg of the bridge
that probably would have saved me.  I paid him for the diagnosis and brought
the amp and supply home.  The bad news is the caps alone are around $800.
Other parts, labor and I am probably looking at $1200 or more.  I don't have
that kind of cash and if I did I'm not sure this would be the most effective
way to spend it.  So, I am trying to figure out my options. 

Any suggestions?

Thanks and 73,
