2-1. SCHEMATIC DIAGRAM
204GD
Note on Schematic Diagram: · 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 and 1/4 W or less unless otherwise specified. · % : indicates tolerance. · C : panel designation. · U : B+ Line.
· Power voltage is dc 9 V and fed with regulated dc power supply from external power voltage jack. · Voltages and waveforms are dc with respect to ground under nosignal (detuned) conditions. · Voltages are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. · Signal path. F : AUDIO
