20 W Stereo Audio Amplifier
– Attach a quick-disconnect terminal to the free end of the slate wire. Connect to the
BIAS
post on the left channel PWB.
– Cut a 20-inch long #22 red 600 V wire. Attach a quick-disconnect terminal to each end of
the wire. Attach one end to the
B+Sense
terminal on the left channel PWB. Route the free
end to the rear of the chassis using the available cable clamp. This wire will connect to the
power management board.
– Cut a 10-inch long #22 red 600 V wire. Attach a quick-disconnect terminal to one end of
the wire. Attach to the
B+
post on the left channel PWB.
– Cut a 11-inch long #22 red 600 V wire. Attach a quick-disconnect terminal to one end of
the wire. Leave this end free; it will be connected to the preamplifier power supply board.
– Combine the red wire prepared in the previous step with the red wire from the B+ post on
the right channel PWB and the red wire from the B+ post on the left channel PWB. Slip
the three wires into a quick-disconnect terminal and crimp. Attach to the B+ terminal on
the rectifier PWB.
– Cut a 10-inch long #22 white wire. Attach a quick-disconnect terminal to one end of the
wire. Attach to the
-60V
post on the left channel PWB.
– Cut a 29-inch long #22 white wire. Combine one end of the wire with the 10-inch long #22
white wire in the previous step. Attach a quick-disconnect terminal (2 wires combined).
Attach to the
-60V
post on the rectifier PWB. Route the free end of the wire power
management expansion PWB using the two rear cable clamps. Attach a quick-disconnect
terminal to the wire. This wire will be connected when the power management expansion
PWB is installed.
– Prepare a 7-inch long #18 black wire. Attach a quick-disconnect terminal to one end of the
wire and connect to the
GND
post on the left channel PWB.
– Combine the 7-inch long black wire and the 27-inch long black wire from the right
channel PWB into a single quick-disconnect terminal. Attach the terminal to one of the
available
GND
positions on the rectifier PWB.
