Comet CV05c - 650n/5

Hooked up to a GME LC200 inductance meter

Watching the capacitance as I turn, not that it matters..
The issue is why does the amp need LOTS AND LOTS of capacitance :)

That's backwards to mine.  Does the screw have right or left hand 
threads. If CCW would be backing the screw out it's pushing the plates 
closer together.  The screw should be held in place so it can only turn 
which pushes or pulls the plates in the opposite direction you'd think 
the screw would be moving.
