Volume and Tone

: The main volume knob controls output level. If the unit includes an integrated equalizer (often labeled GE-5J in this set), you can refine the frequency response across various bands. Kenwood Amplifier A-5j Manual

• Check DC offset at speaker terminals: typically near 0 V DC (within tens to a few hundred mV); consult service docs for exact allowable.
• Check bias current across emitter resistors of output stage (measure voltage drop across small emitter resistors and compute current).
• Measure power supply rails (± voltages) versus no-load expected values.
• Signal injection: use sine generator and oscilloscope to trace signal through preamp, tone, and power stages.
