A friend has an Aqua-Vue which appears to have a broken wire and loose pot.
The problem is how to get the case open. Three people before me have tried
and the case is cracked. There doesn't seem to be a way to slide even a
knife blade between the two parts of the case. I do electronic work and
it'll be an easy repair if I can get the case open. Are these things glued
together. Any suggestions?
