TR4/4A Why is the new voltage stabilizer I got marked with 'top"?

Orientation is important with the electromechanical voltage stabilizers.
Like the slow response Smiths gauges, the mechanism works by internal resistance heating of a bimetallic strip. If you mount the stabilizer "upside down" the effect of the resistance heating can be slightly different than when the unit was calibrated. This can result in slightly a slightly different output voltage than the desired "average" 10V.
The solid-state stabilizers sold by Moss are not subject to changes with mounting orientation and can be installed any way you desire.

It would be interesting to find out. It may be that someone bought repro housings that were so marked, even though it makes no difference to the solid state regulator.
Also seems hard to believe that, given the lousy accuracy of these gauges anyway, that anyone worried about orientation affecting the readings. The heating coil is literally wound around the bimetallic strip and the case is sealed, so the difference would only be whether the weight of the strip pushed it closer to, or farther away from, closing the contacts.
