This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.

Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!

XR-A390
1. SAFETY INFORMATION
LABEL CHECK
IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON.
Printed on the Rear Panel
LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mW WAVELENGTH: 780 - 785 nm
Additional Laser Caution
1. Laser Interlock Mechanism The position of the switch (S9501) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S9501) is pressed physically. Thus, the interlock will no longer function if the switch (S9501) is released physically and deliberatery. The interlock also does not function in the test mode �. Laser diode oscillation will continue, if pin 1 of CXA1821M (IC8101) on the CD ASSY mounted on the $M Loading Mechanism assembly is connected to GND, or else the terminals of Q8101 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam.
� : Refer to page 61 on the service manual RRV2328.
