. RESISTORS:
Indicated in 2, %W, "eW,+5% tolerance unless otherwise noted k : k{2,
M : MQ, (F) : £1%, (G) : +2%, (K) : + 10% (M); +20% tolerance
CAPACITORS:
Indicated in capacity (uF)/voltage (V) unless otherwise noted p : pF
Indication without voltage is 50V except electrolytic capacitor.
VOLTAGE
S] : OC voltage (V) at no input signal
. OTHERS:
=> : Signal route.
@ : Adjusting point.
The mark found on some component parts indicates the im-
portance of the safety factor of the part. Therefore, when replacing,
be sure to use parts of identical designation.
This is the basic schematic diagram, but the actual circuit may vary
due to improvements in design.
SWITCHES:
S1 : POWER ON — OFF
$2: SPEED 33V3rpm — 45rpm
