(In addition to this, the necessary note is printed in each block.) For schematic diagrams. 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 and 1/4 W or less unless otherwise specified. · C : panel designation. · U : B+ Line. · Power voltage is dc 14.4V and fed with regulated dc power supply from BATT and REM terminals on CNP801. · Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : POWER ON * : Impossible to measure · Voltage are taken with a VOM (Input impedance 10 M). Voltage variations may be noted due to normal production tolerances. · Signal path.
