Agreed.
Check out the caps.
Thanks

Does anyone have a schematic for this style power supply? I'm sure I
can figure it out eventually, just hoping I might save some time if
the schematic is available.
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.
