Since the mounting of the Admiral 19A1X chassis chosen for the set is via four screws through the chassis bottom, a vertically-mounted, removable "shelf" would be necessary. The chassis would be bolted to the shelf and then the shelf would bolt inside the cylinder such that the front panel control shafts would extend through holes in the tabletop. Adjustments for brightness, focus, horizontal and vertical hold would need to be considered preset "service" controls unless some means were provided via dial-cord type linkages to facilitate the operation of these rear-apron controls by means of front-panel knobs. Otherwise, there would be no access other than through the back or bottom of the cabinet for making such adjustments. Raster Size, Linearity and Centering could easily remain as "service" controls. In fact, the Vert. Lin. control was a bit of an "afterthought" on the 19A1X series. None is shown in the original Sams literature. A subsequent "Production Change Bulletin" (part of Set #106 IIRC) shows this control added to the circuit.
