Hi Chris,
All noted. I will give your display board the treatment
over Christmas. We are going to do an overnight trip to Milford Sound [Red
boat cruise], but I hope to find time in between opening presents for you
:-)
The cause of damage to the display board might
be due to insulation failure in the 3 conductor "ribbon"
that connects the EHT and [Shock!, Horror!] storage grids to their
respective circuits. Mine has started to "splat" alarmingly, so I`m going to
replace the ribbon with EHT wire [the Teflon inner from some 1/8 inch Teflon
coax - I`ve tested it to 13kV D.C.], and REAL wire for the grids, before I
power the thing up again.
After I`ve gone over your board [and after I`ve fixed the EHT problem in
my unit !], I will fit your board in my 141T, to check that it goes OK, and
then return it to you good as new.
I`ll keep you posted!
Have a good one Chris, and your family to!

P.S. I really apperciate those bits, Chris.
P.P.S. : Have you `scoped and measured the 4 PSU rails?
