PRODUCT SAFETY NOTICE
al should be followed during servicing. Components identified with the IEC symbol A\ in the
Hiagram designate components in which safety can be of special significance. When replac-
ith A\ , use only the replacement parts designated, or parts with the same ratings of resis-
are designated in the parts list in this manual.
e measurements must be made to determine that exnosed parts are acceptably insulated

1. Ail resistors values are indicated in “ohm” (K=10°, M=10%).
2. All capacitors values are indicated in “uF” (P=107"%).
3. All voltages indicated on the schematics are measured under the
following conditions.
a. Use aV.T.V.M.
c. No signals at input terminals
d. AC input at 220 volts 50 Hz
4. This is a basic schematic diagram.
