  • Notes
  • The Rider's Perpetual volume 3 shows the lafayette radios under "Wholesale" instead under Lafayette (as in volume 1 and partly in volume 13 - and as Morgan E. McMahon). The Rider's page 3-3 shows one schematic for M-31 and one for M-35, M-37 and M-53 but lists the latter as M-35, 37, 53 and therefore some editors did believe there are models 37 and 53 ... But it can be read besides the second schematic that M-37 and M-53 is correct.

    For the M-31 the IF frequency is not given but the inductance of the IF coils is 6 M.H. The same applies for the other 3 models on that schematic sheet. See also the model M-31 New Minstrel and the schematic there. This radio model can not be earlier than 1932, because of some tubes used.
