2.2 P.C.B’s PARTS LIST
NOTES:
© Parts without part number cannot be supplied.
@ Parts marked by “®” are not always kept in stock. Their delivery time may be longer than usual or they may be
unavailable.
e The f\ mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
e When ordering resistors, first convert resistance values into code form as shown in the following examples.
Exz.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is
shown by J = 5%, and K = 10%).

noted k; k2,M; MN, (F); +1%, (G); +£2%, (K); +£10%,
(M); +20% tolerance.
2.CAPACITORS :
Indicated in capacity (#F)/voltage(V) unless otherwise noted p;
pF. Indication without voltage is 50V except electrolytic
capacitor.
3.VOLTAGE, CURRENT :
; Signal voltage at 40W-+40W, 8.2/50W+50W, 42
output(1kHz).
L_] : DC voltage (V) at no input signal.
Value in ( ) is DC voltage at rated power.
<mA ; DC current at no input signal.
4.OTHERS :
@ ; Adjusting point
The A\ mark found on some component parts indicates the
inportance of the safety factor of the part. Therefore, when
replacing, be sure to use parts of identical designation.
3 marked capacitors and resistors have parts numbers.
This is the basic schematic diagram, but the actual circuit may
vary due to improvements in design.

Line Voltage Selection (HE and HEWZ TYPES)
Line voltage can be changed with the following steps.
1. Disconnect the AC power cord.
2. Remove the top cover.
3. Change the connection of the power transformer lead wire.
4. Stick the line voltage label on the rear panel.
