SCHEMATIC DIAGRAM Ñ MAIN SECTION (2/2) Ñ D-190/191/191SR/192CK/193 Ð 17 ÐÐ 18 Ð Note: ¥ All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. ¥ All resistors are in W and 1/4 W or less unless otherwise specified. ¥ % : indicates tolerance. ¥ ¢ : internal component. ¥C: panel designation.¥U: B+ Line. ¥ Power voltage is dc 3 V and fed with regulated dc power supply from battery terminal. ¥ Voltages and waveforms are dc with respect to ground in playback mode. ¥ Voltages are taken with a VOM (Input impedance 10 MW). Voltage variations may be noted due to normal produc- tion tolerances. ¥ Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal produc- tion tolerances. ¥ Signal path.
