  • Notes
  • Philco models 751A & 751B are improved versions of the 751 which was released in early 1937.

    The basic circuit is as the 751 & the changes made were a complete reversal of chassis layout and the deletion of components 4, 17 & 21. A 200 pF capacitor was wired between the 75 triode plate & earth, while further change, found in 751B only, is the wiring of component 9 between grid & earth, instead of across the oscillator coil, as shown. A change in value also was made to component 12 to 400pF.
