the jumpers to the pins of the slider.
58. Install R13, the 10K ohm LINE2 pot the same as described in step 57.
59. Install R3, the 10K ohm LINE1 slider pot in the same way as shown in
step 57.
60. Install R20, a 10K ohm surface mounted pot, the last board mounted
part. Make sure to solder all three connections and the two solder lugs.
Wow! we are already finished putting together the kit! Lets go celebrate and
grab a soda or other drink of choice, get an eyeball break and come back in a
few minutes.
Now that you are back, we need to check over the circuit board again for any
misplaced parts. Especially check for diodes in backwards, ICs in the wrong
direction, and capacitors with their polarity backwards. Then check for cold
solder joints and possible solder bridges.
INITIAL TESTING THE MX-5
For this portion of the kit building experience you will need the following items:
Line level source such as a tape deck, signal generator or CD
player.
A destination such as an audio amp, transmitter or earphone
amplifier (Ramsey SHA-1).
A microphone if you are planning on using one.
[1] Connect the line level source to the LINE1 input jacks.
[2] Connect the destination up to the OUTPUT jacks.
[3] Connect a 9 volt battery to the battery jack, making sure the power is off. If
you do not have a battery, use a regulated power supply rated for at least
100mA.
[4] Turn the power on and verify that the destination is receiving your sound.
Vary the levels of the MAIN pot and the LINE1 pot to do this.
[5] Plug the line level source into the LINE2 input jacks.
[6] Vary MAIN and LINE2 pots to verify they work also.
[7] Plug your microphone into the microphone jack. Vary MAIN and L.MIC to
make sure it is operational as well.
