Check  with Murphy's Surplus and see if he still has any power supply

The one I repaired had a bad  controller chip, more details at  
http://www.cliftonlaboratories.com/april_2008.htm -- scroll down about  
half way.

It is possible to work on the module out of the   receiver, but it must 
be done with the appropriate safety precautions and  suitable test gear. 
In general switching power supplies are a major pain  in the backside 
because you don't have (in many cases) a partially working  power supply 
that can be sequentially debugged.

 The
