Does this gearbox have a history of failures?
Has root cause been identified? If a chip
detector has been deemed the most practical
impending failure warning system, does the
generation of metal in the oil flow
pose a risk to the engine? Should the oil
return line be filtered? If so, would it not
be more practical to add a filter with a
chip detector?

| Subject: | Dimmers without switches |
For reasons of size/spacing I ordered 4 potentiometers (5k ohms) with
longer shafts to replace the ones with my VAL CLA 500 dimmer unit. But the
units I ordered do not have a SPST switch that turns them off when rotated
all the way counter clockwise. (The other ones have the switch, but I need
the longer shaft). If I use them, would I need a separate switch for the
dimmer unit, or could I leave the four potentiometers "on" but rotated
fully clockwise while keeping the light off. Would that mean they would be
drawing a continuous load all the time?

How about

instead?
