Montage:
![]() | Here is the Rimshot |
![]() | Solder all resistors. Solder each value one after the other. R334 and R373 are part of the Handclap section and not the Rimshot. Do not mount resistance to the moment at these locations. |
![]() | Solder diodes 1N4148. MAKE SURE DIODES ARE IN THE RIGHT WAY |
![]() | Solder polyesters capacitors and ceramics capacitors |
![]() | Solder electrolytics capacitors MAKE SURE ELECTROLYTICS CAPACITORS ARE IN THE RIGHT WAY
|
![]() | Slightly bend the middle lead of the transistor 2SK30. |
![]() | Solder transistors.Do not get confused between 2SA733, 2SC945 and 2SK30 it is not the same transistors.
MAKE SURE TRANSISTORS ARE IN THE RIGHT WAY |
![]() |
Connect the power transformer. Test 4558 power supply before solder. The green dot is -15V, the red dot is +15 V (plus or minus 5%). You have the ground on the potentiometer big square pad . Always check that the four wires from the power supply is well connected.
THEN DONT FORGET TO DISCONNECT THE POWER TRANSFORMER. DO NOT SOLDER COMPONENT AS THE CIRCUIT IS POWERED ! |
![]() | Solder the 4558s. To insert it into the PCB you have to bend the leads a little. |
![]() | Finally return the PCB and solder potentiometer on the opposite side of components. To assembly the switch, solder one lead of the switch and before soldering the other check that it is well pressed against the PCB. You can then go to HandClap assembly |
