  • Notes
  • The Philco model 645 series (1936) is a follow-on to the 640 series (1935) and uses a 7-tube 3-band chassis with shadow meter (tuning aid). The bands covered are BC, 1.75-5.8 MHz, and 5.75-18 MHz.

    There are two individual models with different cabinet styles. Model 645B is a simple rectangular tombstone with rounded upper corners. Model 645K is a floor-type console with a slightly tapered (trapezoidal) profile.

    The model 37-640 series (1936-37) is electrically very similar, although the latter series has updated tubes and different band coverage.
