Excellent just what I needed to replace the electrolytic caps and make this old gem a beauty again. Was as scan of the original photocopied service manual.
;
It was helpful to get schematic with waveforms in important points and lot of service information. Manual is good quality, fast delivered. Of course it is hardcopy of paper one with all its disadvantages.
 ;
I want to give you a real heads-up for your desire to enable such people as I to acquire the information I need to maintain the older types of equipment such as this Akai HXA351W. You do a swell job with all the processes you have to perform so I can have a legible, thus usable
document which does not send me crazy trying to figure out the blurry text of a bad copy.
Very well done, Thomas.

This manual is very well presented and after printing out looks about as close to an original as I think you can get. The quality is second to none.
The content of the manual is comprehensive and I think it would be well suited to an audio repair professional which I'm not but I did find it very informative and helpful.
The cost of the manual is more than covered by the money I'll save when I change the keep memory battery now I have the relavant info.
Very pleased with my purchase and can recommend it wholeheartedly as I can other manuals I've downloaded from this site.

Complete manual including mechanical part in good pdf quality. Shaded greys of the pcb due to pdf not perfect but usable.
ULTRAMIX SELF TEST PROCEDURE
Setup: Connect the MIDI OUT jack of the DUT to the MIDI IN jack of the DUT. Use Control Interface Port test adapter to connect the TX to the RX signal at the CIP1.
Action: Apply power to DUT. 2
RAM Test: (Tests SRAM and EEPROM) Response: PASS: The three LEDs on the front panel will light up sequentially (MIDI first, then Bypass, then Local). All LEDs will then go off and the Bypass LED will come back on, indicating that the DUT is in its default power-on mode and is ready for normal operation. FAIL: The bottom two LEDs (Bypass and Local Mode) will flash quickly and the DUT will hold in this failure mode.
IO Port Test: (Tests MIDI IO and Control Interface Port IO) Action: Response: Simultaneously apply power to DUT and PASS: All three front panel LEDs should flash at about 4 Hz.4 depress Local Mode switch.3 FAIL: One (or more) of the LEDs remain unlit. Bottom (Local Mode) LED = CIP failure Middle (Bypass) LED = MIDI port failure
Switch Test: ( Tests the front panel switches ) Action: Response: This is a continuation of the IO Port Test. When a switch is depressed, its companion LED will go off as long Depress each switch, one switch at a time. as the switch is engaged. Release the switch and the LED should resume flashing.

C ontrol I ntreface P ort If DUT is already powered up, remove power then reapply power. See Note 2 The LEDs will not be flashing in sync, but that�s ok.
