Serious question, why do so many people skip the capacitor check on old tube radios?
I was fixing a 1950s Zenith table radio from a garage sale in Omaha, and the sound was just a low hum. Everyone online said to replace the tubes first, so I spent $80 on a new set. Still hummed. My buddy who fixes old amps told me to test the filter capacitors with a meter, and sure enough, two were totally dead. Replaced those for $12 and it works perfect now. How many other simple fixes are people missing because they jump to the expensive part first?

You hit the nail on the head with "jump to the expensive part first." It's a classic rookie move, and not just in radios. People see a problem and go for the flashy, known fix without doing the basic checks. That capacitor check is step one for a reason. It saves so much time and money. I learned that the hard way, too.

Yep, swapped a fuse once and felt so dumb.
