Eventually we realised the noise we could just hear over the somewhat
loud Metallica Black album was the rear screen wiper swishing back and
forth across a dry screen.
About 15 years ago I bought a really beat up 1962 Mercedes Benz 190SL
roadster to restore. After I got it home I was checking everything out and
I turned on the radio to see if it worked. Nothing, so I turned it off and
added it to the list of things to fix. Later in the middle of the night I
woke up and realized that the radio was so old that it probably used vacuum
tubes instead of transistors and probably needed to warm up before it would
work. It bothered me so much that I got up at 2 AM and went outside to try
it. Sure enough it was fine after it warmed up for about 30 seconds. My
only excuse is that I hadn't used a vacuum tube car radio since I was in
about 3rd grade!
