  • Notes

  • This model is part of a series of TVs produced by Motorola using the TS-14, TS-23, and TS-52 chassis.  According to Rider TV vol. 5, the TS-14 chassis was used in 10 inch sets with 10BP4 CRT.  The TS-23 chassis was used in 12 inch sets with 12LP4 CRT, and is identical to the TS-14 chassis except for the high voltage transformer.  The TS-52 chassis was used in 16 inch sets with 16AP4 CRT, and is similar to the TS-14 and TS-23 chassis, except for the high voltage transformer, addition of a second 6BQ6 horizontal output tube, and the use of 25L6GT for the vertical output tube.

    There are variations for each chassis type:  For TS-14A and TS-23A, the 3rd IF tube was changed from 6AU6 to 6AG5.  For TS-14B and TS-23B, the video amplifier tube was changed from 6AU6 to 6AH6, and an additional tap was added to the contrast control.  Chassis TS-52 has the same changes as TS-14B and TS-23B.
