Hi Ken. Two thoughts. First, the almost certain culprit is failure of 
one or more of the big HV caps that are in series. Best test I know of 
is an old-fashioned VOM, checking each cap individually with forward and 
reverse measurement, noting the relative charge/discharge current. A 
good cap will have a lot. They can remain in-circuit for the test.

I've needed to do this for two of the three 425s I own. In both cases, I 
only needed to replace one or two of the caps.

Second, I'd be pretty surprised if the schematic differs a LOT from the 
earlier version that's on my website. k9yc.com/publish.htm

I suspect the failure is the result of the caps needing to be re-formed. 
Other list members can provide better advice than I.
