    The Riders manual schematic for this radio refers to it as a model R-110-A.  This number is the chassis number.  Model 1107 is the specific cabinet (case) that uses the R-110-A chassis.



    RF-stage, but the second IF (177.5 kc) has only one tuned circuit (resulting in 6 circuits). The tube 27 is the oscillator and the other the phase inverter for push-pull output. Tube 51 is a noise suppressor.



    Distinctions: Model 110-A is the normal model for 115 volts, 60 cycles. Model 110-B is for 25 cycle mains, 110-E is for 250 volts, 60 cycles. Additional suffix T identifies twin speaker model (field coils in series, voice coils in parallel) - see for instance this R-110AT Side Table and additional suffix F is with phono. This same chassis was used for console models (chair side) and for tombstone models like this model 1107 or tombstone with 2 loudspeakers R-110AT (see the R-110 chassis model page). Since we don't know which variant was used in which cabinet, we can not create models for which we have no evidence. Please tell us if you find more variants for the R-110 series.
