For all practical purposes, component repair is more likely to be
accomplished with current production products. The reason, new boards
in production may have a component failure and they have the staff and
tools to diagnose and replace the parts. Where as older non-production
boards, the test fixtures and skills along with parts availability are
always in question.
Most companies today prefer to do system diagnostics and then board
replacement. The cost of producing a fully loaded and tested boards
today are generally far less than one hour of human diagnostic time.

You could repair a Omni C with nothing more than a mouser part order—you can’t
do that nowadays.
Sources and stocking those oddball parts would be an expensive undertaking, and
would drive up the repair costs.
I’m not sure and might be shooting from the hip, but I’d guess that Icom, Yaesu and
Kenwood repairs are nothing more than swapping out a bad board for a new one. I’m not sure
they do component level repair like Ten Tec does (did!)
Way, way back, I did some apple computer repair on the side. Apple’s service
policy was simple: Try this. Try that. Replace mother board.

There is the physical value of a radio and then there is the sentimental value
of a radio. Clearly in most cases the sentimental value is much much greater
than the physical value. Of course when one needs to get a radio repaired or
when one wants to sell a radio, the sentimental value goes to $0.00 for the
buyer. Likewise for the fellow doing the repairs.
I repaired radios for years for $25/hr, then $35/hr, then $50/hr and finally
$75/hr. The time/labor was a small part of the the price. It was the test
equipment required being the main reason for the price increases. One can no
longer repair a radio with a Black Beauty soldering iron or a Weller soldering
gun and a Simpson 260 VOM.
Yes, we are into a throw-away world.
