I see in the Knowledge Base that the Philco Model 40-201 was introduced in June 1939 and that 9,000 were made. The back of the chassis has Model 40-201, Code 122 stamped on the back of the chassis under the area where the two 42 output tubes are. To the left there are two antenna terminal boards. The smaller 2-terminal board is the inboard terminal and to the right and slightly above that appear these numbers: 1 25 6. I am guessing that this indicates the date of manufacture and a run number? That would mean it was manufactured Jan. 25, 1940 and is Run No. 6. Am I right?
There were two versions of the chassis, one with 11 tubes and one with 10. This one is the 10 tube chassis.
