Remember the Collins 32V-1. Exposed plate caps on the 807s' and 4D-32; but Art
Collins (his engineers) used an interlocking device when you lifted up the lid.
A relatively simple, inexpensive microswitch killed the high voltage.
Collins Radio forever.

What I still wonder even today is how WRL/Leo Meyerson could make such
death

It's my understanding that Leo's designs, tho a bit eclectic, started out OK.
It was his Bean Counters that
messed 'em up.
I still have a Galaxy V that when you life up the lid, there is the PA cage
fully exposed.
I had a Galaxy V Mk. 2 for a couple of years. Not a bad rig, really...
What was he thinking? Could it have been $$$$$ by shaving costs. No
interlocks on the "big boy: - the Globe King 500.
TELL me about it!!! The cost cutting done on that rig is a crying shame...
it could have been one of the
GREAT ones. The most grievous cost cutting measure was in the PA and
modulator plate supplies, IMHO.
They seem to e to be just barely adequate, with PA plate voltage too low;
with another 300 - 500 VDC there
the PA plate efficiency would be a whole lot better.
One thing... Leo's rigs used some FUNNY tubes!
I have a Globe King 400 that's gonna be restored... I had one HELL of a
time finding a pair of V-70D finals!
And the Hytron 5514 modulator tubes (in both rigs) aren't that common
either... tho you can modify for
811As.
