This all started a few weeks ago when my radon fan stopped working due to a ice jam.
It was at this time I found out all 4 of my geiger counters were non functional.
First to get fixed my trusty CDV-700
After a few tests I discovered the high voltage supply to the probe was way off.
Tons of parts out of spec.
Time for a rebuild kit!
part way though the upgrade.
After cleaning and checking everything over multiple times I went to test… voltages are off.. by a bit…
On closer inspection….
That transformer looks fuzzy….??
That isn’t fuzz!?!
Tons of them!
Even on the High voltage potentiometer 1/2 way across
So tiny it is hard to get a good focus on them.
No this is not a hair! That is a tin whisker going from the ground almost to the center of the high voltage adjustment potentiometer.
