ASSEMBLING THE SHA1 HEADPHONE AMPLIFIERS:

Sort out all of your parts to begin with, making sure you have all of the parts required. You can use old egg cartons to hold various parts to make them easier to find. Make sure to mount parts on the correct side! You will want to use the parts layout diagram to assist you in finding where the parts go.

ˆ1. Orient the board in the same direction as the parts layout diagram.

ˆ2. Install C12, a .01uF ceramic capacitor (Marked .01, 10n, or 103)

ˆ3. Install C14, another .01uF ceramic capacitor (Marked .01, 10n, or 103).

ˆ4. Install R2, a 4.7K ohm resistor (yellow-violet-red).

ˆ5. Install R7, another 4.7K ohm resistor (yellow-violet-red).

ˆ6. Using a scrap piece of component lead, install JMP2. These jumpers act as “bridges” over other connections, allowing us to create a well routed PC board.

ˆ7. Using another scrap component lead, install JMP1.

ˆ8. Install C10, a .01uF ceramic capacitor (Marked .01, 10n, or 103).

ˆ9. Install C8, another .01uF ceramic capacitor (Marked 10n, .01, or 103).

ˆ10. Install D1, the 1N4002 rectifier diode. Make sure and install the lined end (cathode) of the diode in the same direction as shown in the diagram. This diode prevents us from accidentally charging an installed battery while external power is applied.
