[time-nuts] Looking for Z3801 Power Supply Board

[Dave M]

Dan,
If you haven't already found the Z3801A page at 
http://www.realhamradio.com/GPS_Frequency_Standard.htm, you should read it 
thoroughly (in your case, especialy the section on the power supply).  there 
is a good pictorial that shows locations of all the power supply test 
points. Using that pictorial, you should be able to determine which power 
supply is causing the problem (there are several).

Otherwise, (I'm sure you're well aware) if you're set on getting a 
replacement PSU assembly, you're probably looking at buying a parts unit and 
salvaging the PSU board from it.  However, you might find that the parts 
unit also has a bad PSU.  It's a chance you take.

Cheers,
Dave M
