5.
Turn off the amplifier.
Amplifier plus speaker plus source tests
1.
Connect a high level source like a CD player to the TUNER inputs.
2.
Turn the volume down.
3.
Turn the amplifier on.
4.
After the relays click in, increase the volume to a comfortable listening level.
Enjoy the music, but don’t get carried away. We still must complete final
assembly.
Final Assembly
1.
Turn the amplifier off.
2.
Unplug the amplifier power.
3.
Reinstall the 5 screws that hold the cover in place.
Your upgraded amplifier is ready for use.
In Case of Trouble
This section contains a list of the most often found assembly errors and their symptoms.
Symptom
Assembly Error
Amp draws too much current, even at idle.
You’ve swapped some of the 2K0 and the
20K0 resistors. That makes the gain too
low, which causes the amp to go unstable,
oscillate, and draw too much current.
Check all of the 2K and 20K resistors for
swaps. If you’re either color-blind, or
uncertain about the colors, lift one end of
any questionable resistor, and measure its
resistance using an ohm-meter.
