M : Mn, (F) : :t. 1%. (G) : :t. 2%, (K) : t 10% IM) ; .t. 20% tolerance
2. CAPACITORS:
Ind icated in capacit y (11Fl/voltage (VJ unless ~therwise noted p : pf
Indication without voltage is 50V except electrolytic capacitor.
3. VO LTAGE, CURRENT :
LJ :
DC voltage IV) at no input signal
Value in ( I is DC voltage at rated power.
<:=,
mA :
DC current
at no input signal
4. OT HER S:
.... : Signal route.
fl} : Adjusting point.
The
&
mark found on some component parts ind~ates the im•
portance of the safety facto r of the pan. Therefore, when replacing,
be sure to use parts of Identical designation.
*
marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may 11ary
