Back in the late 70s and the early 80s when I was doing a lot of
SWL'ing, I had a R-4B receiver that was left on 24/7. It lasted
nearly a decade in such use. Never had a problem during that time
but had power supply problems that ended that long run. Still using
it today but haven't left it

Not really, compared to the heat and _mechanical_ shock each time it's turned on For cathode
type tubes, (most small receiving tubes and some transmitting tubes,) what 'wears out' in a tube is
the electron emitting cathode coating. Weak tubes are often a result of the cathode

I use my R4A about 4 hours a day. Should it be left on continuously or is it
better to turn the radio off every night?

My personal opinion, never leave a vintage rig (especially one with lots of
tubes and high voltages) run
I'm not as paranoid (or as 'safe', I still have equipment with 2-Wire line cords!,) as Jim. I DO
verify that each piece of equipment has the CORRECT fuse.
My rule is that I turn on whatever I want to use in the morning. If I 'think' I'll use it again
during the day, I leave it on until I'm
I did this for the same reason with one R-4B. The one problem was when i
heard a loud bang. Thinking something had fallen on the floor, I found
that an electrolytic cap under the chassis had gone off like a bomb. I
removed the mess, replaced the cap, and all was well.

MY Grandparents had a battery radio Haul that A battery into town for a recharge made you turn
down the filament rheostat as much as possible!

And there's a school of thought that says that 3-wire line cords aren't such a
peacy idea for RF systems. And I'm not as paranoid as Garey about them either.

One place where I will admit being paranoid is regarding fuses. I've heard
horror stories about poorly made fuses that don't blow when they are expected
to, and even
Sorry if this is dumb, but doesn't a tube that is on and the filament on
degrade the tube just by being hot and glowing???
