It's not all of them. I had a 706MKIIG for ten years or so, just sold it
earlier this year, which never had any issues. I took the top off to put a CW
filter in. That's all. The AH-4 that went with it never had any trouble except
operator error and it survived those, too.
I still have a Kenwood 7600 radio I bought about the time of the 1978 ARRL
National Convention in San Diego. It never needed any repair work either. I
put some mods in to make it more useable for t-hunting and it even survived
those without a whimper.
I don't recall any maintenance on my C-Line and L-B, or the FT-101 I had, or
the Heath transceiver before that. My DX-40 had to be rebuilt because my
brother set it on fire tuning up on the wrong antenna. Other than that it
worked pretty well.
Maintenance seems to be a development of the 21st Century.
