FEDBoy Duo 150/3 projector, cont'd

[Elliott Swanson <elliott@xxxxxxxxxxxxxxxxxxxx>]

A few thing to add to the post in the last digest.

The FEDBoy polarizers are between the slide and the lens, which means no 
trouble projecting Polapan or reversed T-Max 100.

The system used to adjust horizontal and vertical skew is a conical head 
on a threaded shaft. As the conical head is screwed in or out, 
adjustments are made by tension between a spring on the adjustment stage 
and the conical head. E.g. the point where the cone makes contact 
determines the position of the horizontal or vertical stage by a broader 
or narrower point of contact on the cone. Worm gears would have been 
nicer, but the conehead system works.

There is a leveling screw at the front of the projector, and two leveling 
screws at the back-- the machine has three points of contact with the 
table top.

In addition to the projection lens, there are three condenser/heat 
absorbing lenses between the lamp and the slide carrier, and there is a 
glass reflector behind the halogen lamp. There are three screws that can 
be used to adjust the position of each lamp independently. Edge to edge 
illumination and sharpness (for the 12 foot projection distance example 
cited yesterday) is excellent.

The projection lenses are FED T3 (2.8/80mm, as mentioned yesterday)

Sinse the manual is in German, there's information I'm missing until a 
friend gets some of the essential parts translated.

The German warranty appears to be 6 months.

The power cord is removable, and is 3 wire grounded.

There is a metal carrying handle recessed into the front of the projector 
for easy carrying.
