Paul,
How's your TR-4 working after replacing the filters?
I always enjoy reading your blog.

Dear OMs on this thread, (Do not try to visualize this)
Here is my report I promised yesterday:
While I was checking cold solder joints, I checked the conductance of the
tuning coil.
The tap in the middle was fine, but the wire was broken near the rear-end
terminal.
The meter would jump a little and then show the infinite R. So I think it
was a very
fine "crack".
Here is a picture that shows what it looked like after I de-soldered the PCB
from the
terminal and lifted the broken end. I soldered it back and now the PTO works
fine.
Thanks for useful tips.
