1. Metal film resistors
R...
R1
: 240K (2 - 4 - 0 - 3 - 1)
R3
: 3K
(3 - 0 - 0 - 1 - 1)
R4
: 4K7
(4 - 7 - 0 - 1 - 1)
R5
: 10K
(1 - 0 - 0 - 2 - 1)
R6

3. IC socket. Watch the
position of the notch!
IC1 : 8p
IC2 : 16p
4. Diode. Watch the polarity !
D1 : 1N4007
CATHODE
5. Metal film resistors
R2
: 18K (1 - 8 - 0 - 2 - 1)
R7
: 1K8 (1 - 8 - 0 - 1 - 1)
Attention : because one of the
connections of both R2 and R7
is a measuring point, it is advis-
able to take care that the body of
the resistors is on the largest
D...
circle of the pcb overprint.
6. Resistor
R8
: 560 (5 - 6 - 1 - B)
