The Marconi Service Manual Vol 1 indicates that the Model 65 was the second production run for the Model 64. To prevent confusion, it appears that Canadian Marconi assigned a new model number for the second production run.
In the second production run, a 1B5 diode-triode was substituted as a second detector and first audio in place of the 1A6. In addition an audio transformer was used in place of an R-C coupling network.
