This is a very good quality print (scan) of the original SONY service manual. The original from Sony is on very thin paper. Nevertheless it is very clear and sharp and excellent readable. I'm very satisfied to have now this rare document. I've looking for it many years (infrequent). It contains very detailed circuit diagrams, exploded views, part lists, PCB view with good readable connection lines. Very recommended.
;
A complete manual with all the needed details of calibrations and service instructions about the radio receiver.
A big deal.
Many thanks !

2. PURITY ADJUSTMENT
No. 1
Adjustment point PURITY ADJ.
Adjustment procedure/conditions 1. Receive the GREEN-ONLY signal. Adjust the beam current to ~700 µA . 2. Degauss the CRT enough with the degausing coil. Note: Follow the Job Instruction Sheet to adjust the magnetic field. Vertical Bv: +0.030 mT (0.30 gauss) Horizontal Bh: +0.020 mT (0.20 gauss) (Reference: page 3-6) Maintain the purity magnet at the zero magnetic field and keep the static convergence roughly adjusted. Observe the points a, b,as shown in Fig. 1-1 through the microscope. Adjust the landings to A rank requirement. Orient the raster rotation to 0 eastward. Tighten up the deflection coil screws. Tightening torque: 108 ± 20 N (11 ± 2 kgf) Make sure the CRT corners landing meet the A rank requirements. If not, stick the magnet sheet to correct it. Note: This adjustment must be done after warming up the unit for 30 minutes or longer with a beam current over 700 µA. Note: Set to service mode by remote controller then press factory process R/C RGB key to change to RGB mono colour mode. For the following colours press R/C RGB(Hex 7E) key to change.
