4. SCHEMATIC AND PCB CONNECTION DIAGRAMS
NOTE FOR SCHEMATIC DIAGRAMS Type 2A
1. When ordering service parts, be sure to refer to
"PARTS LIST of EXPLODED VIEWS" or "PCB
PARTS LIST".
2. Since these are basic circuits, some parts of them or the
values of some components may be changed for improve-
ment.
3. RESISTORS:
Unit: k:kQ, M:MQ, or Q unless otherwise noted,
Rated power: 1/4W, 1/6W, 1/8W, 1/10W unless otherwise
noted,
Tolerance: (F): :11%, (G): :12%, (K): :110%, (M): :120% or :15% un-
less otherwise noted,
4. CAPACITORS:
Unit: p:pF or !1F unless otherwise noted,
Ratings: capacitor (!1F)/ voltage (V) unless otherwise noted,
Rated voltage: 50V except for electrolytic capacitors,
5. COILS:
Unit: m:mH or !1H unless otherwise noted,
6. ,VOLTAGE AND CURRENT:
L: or - V:
The -14dBV (1kHz) signal on the CH1 (LINE) side is
shown by the DC voltage (V) at the time of input.
~ mA or - mA:
DC current at no input signal unless otherwise noted,
7. OTHERS:
. ø or 0 : Adjusting point.
. .. : Measurement point.
. The & mark found on some component parts indicates the im-
portance of the safety factor of the parts. Therefore, when re-
placing, be sure to use parts of identical designation,
