OWNER’S MANUAL
/ IMPORTANT SAFETY
INSTRUCTIONS
Verify Line Voltage Before Use The Citation speaker has been designed for use with 100- 240 volt, 50/60 Hz AC current. Connection to a line voltage other than that for which your product is intended can create a safety and fire hazard and may damage the unit. If you have any questions about the voltage requirements for your specific model or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet.
Do Not Use Extension Cords To avoid safety hazards, use only the power cord supplied with your unit. We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets, or place heavy objects on them. Damaged power cords should be replaced immediately by an authorized service center with a cord that meets factory specifications.
Newest Added: TBT18TABMRAAPSW23PSSCSSJV348L2SSJBP67SH2SSJBP80WH1WW
Handle the AC Power Cord Gently When disconnecting the power cord from an AC outlet, always pull the plug; never pull the cord. If you do not intend to use your speaker for any considerable length of time, disconnect the plug from the AC outlet.
Do Not Open the Cabinet There are no user-serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your warranty. If water accidentally falls inside the unit, disconnect it from the AC power source immediately, and consult an authorized service center.

You can see the service manual here:The problem is no audio from the right channel. The problem occurred aftera lightning-induced power surge so I assume that was the cause. I expected to find bad output transistors but that was not the case.
I believe the problem is not related to the protection circuit as I removed Q402 and disconnected 2 leads from Q418 (there is a brief description of the protection circuit on page 4 of the manual).With an audio signal connected, I can see the the signal at Q404 & Q412 matching the left channel. At Q406 & Q458 the signal is gone.Measuring some voltages I found Q420 to have -81V (E), -80V (B), +81V (C) compared to -6.7V (E), -6.1V (B), -6.4V (C) for Q419 on the left channel. Also, the +/-1.2V on the collectors of Q422, Q426, Q424, & Q428 is not thereand I cannot figure out where it is supposed to come from. Note that the rail voltages measure about 80V as opposed to the 58V shown on the print (that is only for the Japan model I think).Suggestions?
