SREIO Board issue 1 & 2 Parts List

Important Note

The 1/4” sockets are fitted on the underside of the board. They should be fitted last and soldered
from the top side of the board.

Resistors

All resistors 1% 0.25W metal film resistors.

220R

R2, R3

2K2

R5

3K9

R6

10K

R4

39K

R7

Issue 1: R1 can either be a 0R resistor or simply a wire link made from a resistor lead clipping.

Issue 2: There is no R1 but you need to fit three wire links to positions LK1, LK2 & LK4. The
position LK3 must be left empty.

Capacitors

100nF axial multilayer ceramic

C1

2u2, 63V electrolytic

C2

22uF, 35V electrolytic

C3

Discrete Semiconductors
