I started working on radios and such when I was young (around 4 ) My uncle worked for RCA at Cape Canaveral and my Dad was an Electrician. So I had all kinds of cool things to play with. Then when I was in my 20's I used to collect and restore them. I just love the old stuff!

Kinda off topic, but I know Morse code! I spend a little over 2 hours a day on a school bus... learning the code kept me busy for a couple days. :D

I always take them apart and check things out 1st. This way if I see any thing obvious like bad wires,moisture or anything bad like that I can catch it before It goes up in flames or burns something out.

I learned the hard way long ago. any electronics that have been sitting for years... take it apart and check everything.

Good advice Chris. I would add that the most likely components to fail at power up are the electrolytic filter capacitors. They have a definite lifespan and some last longer than others. If they short it can be quite damaging to other circuitry. If they loose their capacitance then you will get buckets of hum.
I have worked on tube gear all my career in a limited way. It's only been the last couple of years that all the tube stuff was retired from the lab. I have built a big tube power amp for my own use. It's a bit of a hobby for me as well as a career. Much of the tube stuff I worked on was very well designed and easily out lasted early solid state efforts.
