Ramsey Electronics SHA1 manual ˆ28. Install J1, one of the RCA type jacks

usually indicating the negative (-) terminal of the component. You will notice on the parts layout diagram that the hole for the positive terminal is denoted, not the negative one. You will want to install this component with the positive (+) lead in the same orientation as shown in the parts layout diagram. If you do not install it correctly, you will end up with all sorts of problems in the circuit.

ˆ23. Install C3, a 220uF electrolytic capacitor. Again pay close attention to the orientation of this component!

ˆ24. Install C7, another 220uF electrolytic capacitor. Again note the orientation.

ˆ25. Install C6, a 10uF electrolytic capacitor. Orientation!

ˆ26. Install C1, the remaining 10uF electrolytic capacitor.

ˆ27. Install J3, the 1/4” earphone jack. Make sure all the pins are soldered for good mechanical stability.

ˆ28. Install J1, one of the RCA type jacks.

ˆ29. Install J2, the other RCA type jack.

ˆ30. Install S1, a DPDT switch. Make sure the part is mounted flush to the board before soldering all six pins.

ˆ31. Install S2, the other DPDT switch.

ˆ32. Install R3, one of the 10K ohm potentiometers.

ˆ33. Install R6, the other 10K ohm potentiometer.

ˆ34. Using a scrap piece of component lead, make a jumper that mounts through the holes where the battery is to be mounted. Thread the jumper through the metal 9V battery holder and then solder the jumper to mount the clip to the PC board.
