| Intermittent's:
How to find them
How
to quickly and easily isolate faulty
components! If you have one channel down or cutting
out: THE FIRST THING TO DO IS VERIFY IF MORE THAN ONE SOURCE IS BAD, I.E.; TUNER, CD, TAPE ETC.... IF AND ONLY IF THIS IS THE CASE, JUMP TO AND PROCEED WITH BELOW steps, starting at #1. IF THE PROBLEM IS ONLY ON ONE SOURCE..... If the problem is only on ONE source only (cd, phono, tuner etc., REVERSE the positions of the plugs coming FROM the defective source component WHERE THEY ENTER THE PREAMP OR RECEIVER. MAKE SURE YOU TURN THE VOLUME DOWN ALL THE WAY FIRST: DO NOT TURN OFF THE UNITS !! If the problem changes channels, the external component or cables are bad. Note WHICH channel is NOW defective, turn the volume down again, and REVERSE POSITIONS the plugs at the back of the external componenet you are testing. Now, if the defective channel REAMINS on the same side as the last test, the cables are bad. If it changes sides, the component is defective. IF YOUR SYSTEM HAS ONE CHANNEL INTERMITTENT OR OUT TOTALLY ON ALL SOURCES.....THEN....... If the problem is on multiple sources, AND THERE IS A TAPE DECK USED, disconnect the tape deck cables COMPLETELY from the receiver or preamp, to determine that the deck or cables are not causing the problem. Yes, a bad tape deck or cables can cause channel problems. IF THAT DOESNT SOLVE IT.....THEN....1)NOTE DOWN which channel/speaker is bad. Turn off amplifier POWER.
2) Reverse the positions of the SIGNAL INPUT PLUGS at the back of the AMPLIFIER, and turn it back on. > If the problem remains on the same SPEAKER, the Amp *MAY* be defective. Go to STEP 3 If the problem SWITCHES speakers, then go down to STEP 4 3) To eliminate the speakers and wires from being the problem, note which channel is defective NOW, TURN THE AMP OFF, and reverse the speaker wires at the BACK OF THE AMPLIFIER by moving the RIGHT CHANNEL WIRES TO THE LEFT ouputs, and LEFT>RIGHT. Turn it back on. If the problem stays on the SAME SPEAKER, the speaker or wire on the BAD side is defective. If it reverses, its the amp. If you did step 2 as above.... then.... 4) If the problem changes sides, the preamp, cables, or associated equipment is at fault. Note the bad side, turn the amp off, and reverse the plugs (that feed the amp) AT THE BACK of the PREAMP (left to right, and right to left). Turn the amp on. If the problem remains on the same side, the CABLES BETWEEN THE PREAMP AND AMP are defective.......if THE PROBLEM SWITCHES SIDES, THEN....THE PREAMP IS DEFECTIVE.
