OK, I didn't know about that one. I assume it's a monochrome unit (the
DY802 won;'t supply enough current for a colour CRT (except possibly as a

stabilisation.
[1] At least one colur TV in Europe, I think it was the Philips G6
chassis, used an EY51 for the focus rectifier, along with the normal
GY501 for the final anode.

I doubt you'll find valve rectifiers and the
'shunt stabiliser triode' in
any computer monitor, though ;-)
And what about a DY802 in a Telefunken SIG100 computer graphics terminal?
But admittedly it dates from the early 70s. And there's no PD500 of
course.
