RE: Svetlana 6550 Identificiation

The "square" holes were only present on the 6550C version. The earlier 6550B and others had small round holes in the plate.

The "square" holes were made to allow a screen alignment tool to be used at the factory. The early versions had a lot of issues with misaligned screens. the "C" version did not.

Check out the thread I linked to below for more info.
