SECTION 3 DIAGRAMS
3-1. CIRCUIT BOARDS LOCATION
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) For schematic diagrams.
Note: â¢ All capacitors are in ÂµF unless otherwise noted. pF: ÂµÂµF 50 WV or less are not indicated except for electrolytics and tantalums. â¢ All resistors are in â¦ and 1/ 4 W or less unless otherwise

U : B+ Line. V : Bâ Line. H : adjustment for repair. Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : POWER ON â¢ Voltages are taken with a VOM (Input impedance 10 Mâ¦). Voltage variations may be noted due to normal production tolerances. â¢ Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. â¢ Circled numbers refer to waveforms. â¢ Signal path. F : TUNER
