Are you aware that that model is listed in Sams 4180? It is listed as "version A", I do not know what version you have. (nor do I understand why they have different versions of the same model that can be quite different) Looking at the schematic it appears to be the same as a Orion TV1926AW (version C) in Sams 3952,also the same as Westinghouse WT1902.
