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 !

H. MAGNETRON REMOVAL
1) Disconnect the leadwire from the high voltage transformer and high voltage capacitor. 2) Carefully remove the mounting screws holding the magnetron and the waveguide. 3) Remove the magnetron ASS'Y until the tube is clear from the waveguide. NOTE: 1. When removing the magnetron, make sure its dome does not hit any adjacent parts, or it may be damaged. 2. When replacing the magnetron, be sure to install the magnetron gasket in the correct position and be sure that the gasket is in good condition. 3. After replacing the magnetron, check for microwave leakage with a survey meter around the magnetron. Microwave energy must be below the limit of 5 mW/cm2.(With a 275 ml. water load). Make sure that gasket is rigidly attached to the magnetron. To prevent microwave leakage, tighten the mounting screws properly, making sure there is no gap between the waveguide and the magnetron.
