Tom:
If you decide to refurbish your AN/URM-25D, there's an excellent 
article in the Hollow State Newsletter, written by Dallas 
Lankford.  The generator is inconveniently small for easy repairs, 
and the article guides you through refurbishment, avoiding many 
pitfalls.  I worked on mine, replacing almost all capacitors (because 
they were bad, not a shotgun replacement), most resistors, and the 
germanium diodes.

The Hollow State News stopped publication around 2002 as the Internet 
became more popular, and I think Dallas is no longer active.  He 
wrote many interesting articles in the past, and I'm guessing he was 
involved in refurbishing AN/URM25-D's used at an University in Texas.

Maybe someone has the article on-line.  If not, and if you are 
interested, I'll scan mine.
Jim

Does anyone know of an Internet source with this info.  It would save 
me scanning time.  My scanner doesn't have a feeder.
