Motorcraft Double Platinum Plugs
I got a new lens for my D70 today, so I thought I would try it out taking pictures of the electrodes on a used DP plug (with 50K miles) comparing it
with a new DP plug:

Nice pics, Bob. A lot better than the ones in the Haynes Manual! I'd say your new lens is working quite well.
It'd be interesting to have a pic of a non-DP 50k used plug to put side by side with those.

Thanks Jim, here are some more pictures I took with it of a PCB. Let's see if
anybody recognizes what this PCB is out of (people on my FTE mailing list
are excluded on this question) ...ha ha ha ha

But I suppose there are people who might kid around with me in the same fashion. 
Bob, like many other people, I'm interested in seeing the pics of the radio display repair.

Joe, here is the URL for my photo site with some pictures (before and after).
There are some pin-thru-hole resistors that run hot, you can see those solder joints. There is also a shield that provides a GND connection from one
end of the board to the other, and you can see those solder joints were cracked also.

Bob, looking over those pictures I was wondering if the solder breaks were obvious or if you had to search them out with some sort of magnifying glass? Would a regular solder pencil work once the breaks are identified?

The shield tabs were pretty obvious, when I used the shield it to lift the PCB out, one end came up! I have a round fluorescent work light with a big magnifying glass in the middle that helps with inspecting small SMT devices. A low power (25W) soldering pencil works well. Have a good week, and keep in touch Joe!!

A job well done I might add.
Not knowing electronics- were the "pin-thru-hole resistors that run hot" melting the solder connections & about to cause a problem too?
Something tells me that this may not have been a do it yourself repair for me anyway, even with my solder pencil & magnifying glass.

After seeing the pictures of the PCB, a friend asked if my new lens would have the resolution to see Lincoln, in the Lincoln memorial, on the back of
a penny. I gave it a try, judge for yourself!!!
