Subject: [Drakelist] L-4B load capacitor
I acquired the L-4B from ebay. It is in overall good
condition but the load variable capacitor does not have
enough shaft friction to hold the plates in position.
There appears to be an adjustment screw on the back of the
capacitor but there is no easy way to access the screw.
Does anyone know a way to adjust the shaft friction of this
capacitor without pulling the load capacitor and the fan?
Thanks for the help
Check to see if there is any end play in the rotor
shaft. If there is you will have to adjust the bearing. If
the rotor has no play and seems reasonably well centered
look at how its connected. Most rotors use some sort of
brush contact. This may introduce some friction. If its got
oil or grease on it cleaning may increase the holding
friction a bit. Otherwise I agree about using felt washers
under the knob.
