The other trick in the old days was the picture tube

connector and the CRT to boost
the filament voltage and run the cathode hotter.
After the CRT deteriorated
further you might have it re-gunned.
I obtained a brand new one of these, probably
specific to a particular make/model, but don't ask me
which (it ain't in front of me). I had also heard that
there's something called an "age switch", but I have
to wonder if the guy was pulling my leg, cuz I never
found one. But possibly it employed a technique like this?
