Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.

Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
Power Amplifier
SETTING INPUT SENSITIVITY 1. Initially turn the INPUT LEVEL control(s) to minimum (counterclockwise). 2. Reconnect the (�) negative lead to the vehicle�s battery. Apply power to the audio system and play a dynamic music track. 3. On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o�clock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard. NOTE: After the source unit is on, blue LEDs (on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit. Also refer to �Troubleshooting� on the page 7.
Reference 5760a/5761a
REMOTE LEVEL CONTROL (OPTIONAL) All three Reference subwoofer amplifiers and the 5760a/5761a amplifier have inputs for an optional remote level control (100rc). This will allow the subwoofer level to be adjusted from the listening position. Connect the optional remote level control using the RJ-11 jack on the side of the amplifier. Install the control module in the front of the vehicle within easy reach of the driver. Both the underside of the dash and the center console are suitable locations. Refer to the mounting instructions accompanying the 100rc. SETTING THE BASS BOOST The5760a/5761a are all equipped with a bass-boost control. This allows you to enhance the bass output of your system at 50Hz up to 12dB.
STATUS LEDs Clip: Indicates the amplifier is being overdriven, and your speakers may be in danger. This should blink only on musical peaks, and not be on constantly. Power: Indicates the amplifier is on. Protection: Refer to �Troubleshooting� for specific indications. Figure 15. LED status.
AUX OUTPUT Reference amplifiers 5760a/5761a are equipped with full-range outputs that can be used to connect additional amplifiers. NOTE: When using the low- or high-level inputs, the AUX outputs can be used to pass a full-range line-level signal to another amplifier.
