• Notes

• The RCA 9PC41a is an AC operated, 41 tube b/w Projection TV console with US standard VHF Tuner channels 2 thru 13. A reflective optical system provides a 15" x 20" picture on the screen. Equipped with RF/IF chassis KCS24C-1, horizontal deflection chassis KRS20B-1, power supply chassis KRS21A-1, audio amplifier chassis RS123C, optical barrel chassis KRK4 and picture tube 5TP4.  The optical barrel chassis KRK4 is used only for the optics and contains no tubes.

  There are three versions of model 9PC41.  The RCA Redbook documentation lists them as 9PC41a, 9PC41b and 9PC41c, but also notes that the actual lables on the models are not labeled as such.  Thus the actual model must be identified per the table below:

  Model Number	RF/IF Chassis	Lighted Channel Marker	Cabinet
  9PC41a	KCS24C-1	No	Walnut, Mahogany, Toasted Mahogany
  9PC41b	KCS24D	Yes	Walnut, Mahogany
  9PC41c	KCS24D	Yes	Toasted Mahogany

  Also note that the 9PC41c has a different interlock switch and hinge lid support compared to the 9PC41b.

  The RCA Redbook documentation states that the alignment information for these models is found in the service data for model 648PTK.
