I recall some TO220 BUXXX being high voltage transistors used in TV sets (CRT times).I've just come across something else which I can't find datasheets for, I know they are from Philips - it says so on the tubes which read.
Philips - Made in Hong Kong.
9336 498 80127
ON962
(50) N451 GC --- and this is the only place in which the tubes differ -- 8914 on one tube 8923 on the other.
I have included the components themselves in the picture.
Also on one of the tubes and I don't know if this is in any way related is written in marker 7808 => 200/u.
The closest I have managed to come up with is a BU508V Which is one letter short of the code.
OH BTW I managed to FINALLY find if anybody wants them the Datasheets for the Krypton Isolation
