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.

El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.
SECTION 3 SET-UP ADJUSTMENTS
� � �
When complete readjustment is necessary or a new picture tube is installed, carry out the following adjustments. Unless there are specific instructions to the contrary, carry out these adjustments with the rated power supply. Unless there are specific instructions to the contrary, set the controls and switches to the following settings : Contrast .................................. normal
Carry out the adjustments in the following order : 3-1. Beam Landing and Geometry. 3-2. Convergence. 3-3. Focus. 3-4. White Balance. Note : Test equipment required. 1. Color bar/pattern generator. 2. Degausser. 3. Oscilloscope. 4. Digital multimeter.
Brightness .................................. normal
3-1. Beam Landing
Preparation : 1. 2. In order to reduce the influence of geomagnetism on the set�s picture tube, face it in an easterly or westerly direction. Switch on the TV set�s power and degauss with a degausser. (2) Landing and Geometry Note : Before carrying out the following adjustments adjust the magnets as indicated on page 22 [See Fig.3-4]. 1. Input a crosshatch signal from the signal generator. 2. Rough-adjust the focus and horizontal convergence. 3. Switch from the crosshatch pattern to an all-red pattern. 4. Move the deflection yoke backwards and adjust with the purity magnet so that the red is at the centre and it aligns symmetrically [See Fig.3-5]. 5. Move the deflection yoke forward to the point where the entire screen just becomes red [Mark its position]. 6. Move the deflection yoke further forward until the screen just changes colour at the edges. [Mark its position]. 7. Position the deflection yoke between the two marks indicated above. 8. Input a crosshatch pattern from the pattern generator and rotate the deflection yoke so that the horizontal lines are parallel with the top and bottom of the screen. 9. When the position of the deflection yoke has been determined, fasten it with its fixing screw. 10. Once dy rotation and swing left and right for h linearity is ok on cross hatch pattern, insert dy wedges. [See Fig.3-6]. 11. Switch the pattern generator to green then blue and confirm the purity. 12. If the beam does not land correctly in all the corners of the screen, use disk magnets to correct it. [Confirm the corner landing forgreen and blue]. 13. Re-check geometry for landing magnet effect. Adjust using deflection menu. [TT Mode].
(1) Adjustment of Correction Magnet for Y-Splitting Axis. 1. 2. 3. 4. 5. 6. Input a crosshatch signal from the pattern generator. Set the Picture control to minimum and confirm that the Brightness control is set to normal. Position the neck assembly as indicated in Fig.3-3. Loosen the deflection yoke fixing screw. Move the deflection yoke as far forward as is possible. Adjust the upper and lower pin symmetrically by opening or closing the Y-splitting axis correction magnets located on the neck assembly. [See Fig 3-2] Return the deflection yoke to its original position and re-tighten its fixing screw.

Caution : High voltages are present on the Deflection yoke terminals - take care when handling the Deflection yoke whilst carrying out adjustments.
