I used to keep my SX-62 turned on for nearly all the time I was at home. I
like radio, and the 62 is a general coverage receiver with low VHF and FM.
There's always something to hear on it. It's been on for over a couple of
days several times. If the radio is in good condition, there is no limit.
The power tubes, such as the rectifier and audio output tube, will last
thousands of hours. The small signal tubes will last tens of thousands of
hours.

That should be fine. I've always have some radios stacked and it's never
been a problem. Actually, the heat probably wouldn't bother most plastic
radios, either. I'll bet they'd get hotter in the direct sun.

Should be fine. Many tube radios also had wood cabinets.

Put the radio where it's convienient. If other electronics interfere with
the radio, turn them off. The radio won't interfere with the other
electronics.

It's lasted a long time without a fan, and it should last yet longer without
one. Most of my radios are from forty to sixty years old, and none of them
have fans. I consider all of them relible enough to leave powered up
indefinately. And, if one of their transformers or something should go up
in smoke, I really doubt a fan would have helped.
