INITIAL TEST
Visually inspect the Guitar Amplifier wiring.
In particular, make sure all connections are
soldered and that bare wires and component
leads are touching only the points they connect
to.
Check the circuit board to make sure there are
no solder bridges between adjacent foils. If you
find a solder bridge, refer to the Kit Builders
Guide for information on correcting it.
If an ohmmeter is available, we suggest
that you make the following resistance check to
make sure that the power supply circuit is wired
correctly. If the ohmmeter reading is any lower
than 1200 ohms, there is aproblem in the wiring
that must be corrected before you operate the
Guitar Amplifier. NOTE: The internal wiring
of some ohmmeters is such that it will be
necessary to reverse the test leads to get the
proper resistance reading. Try the test leads
in both directions and use the higher reading.
( )
Set the ohmmeter range switch at RX100,
connect the common test lead to the chassis,
and connect the positive test lead to TP-G
(see the X-Ray View, fold-out from Page
38). Wait until the meter indication stops
increasing, and then read the resistance.
Reverse the test leads and repeat the
measurement. If the highest reading you
obtained was more than 1200 ohms, pro-
ceed to Final Assembly; if your highest
reading was less than 1200 ohms, use the
information in the In Case Of Difficulty
section to locate and correct the diffi-
culty before you proceed to Final Assembly.
