[Mgs] Old Car Radios

Bob,
Your radio story reminds me of the following:
1. During half of my student days, I drove a 1972 Sunbeam Sceptre
(similar to a Hillman Hunter, you can google that).
That was until 1981, when I graduated and started working. In those
days, it was not done, as a sales rep, to drive a 10-yr old car.
So I bought a Peugeot 504, archetypical for a sales rep in those days.
Since the Sunbeam's manufacturer had gone belly up and, by
consequence, the resale value was very very low,
and the car looked still quite good, I decided to not trade it in
but just keep it.
Fast Forward 30+ years: I got the car running again and nowadays
make occasional trips with it,
like e.g. a camping trip to the South of England with my son.
Three things that I noticed when I drove this car first time after
so many years:
a. The steering wheel rim is very thin;
b. Panorama view: no thick posts between windscreen and doors etc.
c. The (Grundig, upmarket for its days) AM/FM monaural radio sounds
really terrible when compared to more modern gear.
2. In the late seventies, I worked for three months as a trainee at
Televerket, the Swedish telephone company.
Of course, my internship required that I do something scientific,
but due to poor organisation by my employer, a state enterprise,
I could not work for weeks at the project that I came for.
So, colleagues came by and asked me if I could repair their record
players, stereo's, car radios etcetera.
Now, this was not a skill I had any experience with, but at that
age you learn quickly.
These were the days before Internet or even telefax.
But, when you grab a telephone and ask the manufacturer to send
some circuit diagrams by mail,
they were really very eager to assist such an important institution
like the Swedish Telecom authority.
So, I repaired a lot of electronics stuff then, and learned a lot
in the process.
One day, I had a small problem with the Sunbeam, no output from the
alternator (Lucas 16 ACR).
Not very nice to work on, when it is minus 25 degrees Centigrade
outside.
No problem: I could easily drive the car into the Televerket
laboratory after working hours
and replace the carbon brushes that my brother had sent me by mail
from Holland.
Cheers
Bert
