M:Mo, (F): rl%, (G):r2%, (K): t1096.(M| :12Ot(tolerance
2. CAPACITORS:
Indicated in capacity (pFllvoltage (V) unless otherwise noted p : pF
Indication without voltage is SOV except electrolytic capacitor.
3. VOLTAGE
E , DC voltage (V) at no input signal
4. OTHERS:
{: Signal route.
@ : Adjusting point.
The 7\ mark found on some component parts indicates the im-
portance of the vfety factor of the part. Therefore, when replacing,
be sure to use parts of identical desiqnation.
This is the basic schematic diagram, but the actual circuii may vary
due to improvements in design.
