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.
Fast access, 100% correct and complete service manual

â¢ Power voltage is dc 9 V and fed with regulated dc power supply from external power voltage jack (J4). â¢ Voltages are dc with respect to ground under no-signal conditions. â¢ Voltages are taken with a VOM (Input impedance 10 Mâ¦). Voltage variations may be noted due to normal production tolerances. â¢ Signal path. F : AUDIO J : RF
