A lot of old car radios used a 262.5 KHz IF to prevent image

Old being before what year? I was just a young pup learning back
in the 70's so I don't recall a 262 IF. Probably too much LSD
later on.


Delco was still using 262.5 in the early '70s. I could repair
most
of their mid '60s to mid '70s AM radios in less than 15 minutes.
Some took less than 5 minutes. I still hve most of the H.W. Sams
AR series manuals. The cheap Japanese radios used either 450 or
455 KHz IFs, which caused problems on 900 or 910 KHz.

Well that makes sense. I got pretty good on the Delco stuff. Mostly
bad tubes, suppressor caps, stuck vibrators, things of that nature.
Tweaking the receiver I usually did by ear going through each stage
from start to finish. Then the antenna trimmer once it was back in
the vehicle. I'm sure I have an old tube radio and a few parts up in
the attic. Used to have one on my bench for music.


I gave away about 200 '50s through '70s car radios when I moved
south, 25 years ago. Now, most are worth $100 to $1000.

Doesn't that **** you off.


I had a choice of bringing my tools, parts and manuals, or the
radios. I made a lot more money from using the tools. I hauled a little
over 17,000 pounds of tools, parts and manuals 1,000 miles, in two
trips.

Was a semi with a 60, lbs load limit too much money one way?
