I had been listening to Short-wave for almost 10 years. I have both
digital & transistor modest radios. But no tube radio. (Yet)!

What I mean by Which Tube Radio:

If I bought myself an old used Tube Radio, I would exspect some of the
tubes will eventually burn out, and I would have to replace the tubes in
order for the radio to work.

So, that I could have a radio that I could always find the right tube,
means that I would have to buy a radio that it's tubes are still being
made by a company.

There aren't any companies making the tubes anymore that you will find
in a tube radio.

I do not think that I would want to get a radio that I can not replace
it's tubes.

In reference to my comment above, there is a large inventory of tubes
still available and many sources to purchase from.

So, which brands or models should I look out for?

Look for the general coverage communications type of receivers, brands
such as Hallicrafters, Lafayette, National, Hammurlund (sp?), Heathkit,
Collins (pricey), RME, Drake, ect.

And when did they stop making tube radio? (Dah) And why do they still
make tubes if they do not make radios for them?

When transistors were developed that could operate at high frequencies,
late 1960s early 1970s everything started to go solid state.

Do they make all of the tubes?

No.

As a newbie in tubes learn more about tubes?

Pick up an earlier edition of the ARRL Handbook for Radio Amateurs.
