very helpfull
circuit diagram and sparepart list available
 ;
Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.
;
It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

It was complete service manual with all needed service informations. Thanks.

INSTALLATION AND SERVICE INSTRUCTIONS
Note: (1) When performing any adjustments to resistor controls and transformers use non-metallic screwdrivers or TV alignment tools. (2) Before performing adjustments, the TV set must be on at least 15 minutes.
CIRCUIT PROTECTION
The receiver is protected by a 5.0A fuse (F701), mounted on PWB-A, wired into one side of the AC line input.
HIGH VOLTAGE CHECK
High voltage is not adjustable but must be checked to verify that the receiver is operating within safe and efficient design limitations as specified checks should be as follows: 1. Connect an accurate high voltage meter between ground and anode of picture tube. 2. Operate receiver for at least 15 minutes at 120V AC line voltage, with a strong air signal or a properly tuned in test signal. 3. Enter the service mode and select the service adjustment "S19" and Bus data "01" (Y-mute on). 4. The voltage should be approximately 32.8kV(32RS50, 32R-S400, CR32S40)/33.4kV(36R-S50, 36RS400) (at zero beam). If a correct reading cannot be obtained, check circuitry for malfunctioning components. After the voltage test, make Y-mute off to the normal mode.
X-RADIATION PROTECTOR CIRCUIT TEST
After service has been performed on the horizontal deflection system, high voltage system, B+ system, test the X-Radiation protection circuit to ascertain proper operation as follows: 1. Apply 120V AC using a variac transformer for accurate input voltage. 2. Allow for warm up and adjust all customer controls for normal picture and sound. 3. Receive a good local channel. 4. Connect a digital voltmeter to TP653 and make sure that the voltmeter reads 13.8 ±0.7V (32R-S50, 32RS400, CR32S40)/13.2 ± 0.7V(36R-S50, 36R-S400). 5. Apply external 17.0V DC (32R-S50, 32R-S400, CR32S40)/ 16.2V DC (36R-S50, 36R-S400) at TP653 by using an external DC supply, TV must be shut off. 6. To reset the protector, unplug the AC cord and plug the AC cord power on. Now make sure that normal picture appears on the screen. 7. If the operation of the horizontal oscillator does not stop in step 5, the circuit must be repaired before the set is returned to the customer.
