Another thing you can do is get some flexible rubber/plastic hose and make your self an HV stethoscope...

That's an awesome idea. I am pretty sure I have some in the garage which I used for listening for bad bearings in cars.

I cleaned up the divider a bit, I can't see any cracks, but when I put my high voltage probe close to the divider I can hear static like sounds.

After cleaning it up a bit the sound seems almost gone.

The response I got from the vendor I contacted was he no longer stocks NEC parts due to most of them having bad caps by now.

If you get a grounded screw driver around any hole
it will draw a full arc. Using meter wont as a rule.
Also a humdid day will make it arc.
For cleaning 91% isopropyl alcohol is dirt cheap &
evaporates fast with no residue. Also great for VCR
& audio heads & paths. BUT rumored to harm some CD lenses.

good luck

LFOD !

BTW that divider may be used in regular projo sets from other
makers too !
