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.
2.4 Service position This unit has been designed so that the Mechanism and Main board assemblies can be removed together from the chassis assembly. Before diagnosing or servicing the circuit boards, take out the major parts from the chassis assembly. 2.4.1 How to set the �Service position� (1) Refer to the disassembly procedure and perform the disassembly of the major parts before removing the Mechanism assembly. (2) Remove the screws that fix the Mechanism assembly to the Chassis assembly. If any other screws are used to fix the boards, remove them also. (3) Remove the combined Mechanism and Main board assemblies. (4) If any other major parts are used, remove them also. (5) Connect the wires and connectors of the major parts that have been removed in steps (1) to (4). (Refer to Fig. 2-41a.) (6) Place the combined Mechanism, Main board and other board assemblies upside down. (7) Insert the power cord plug into the power outlet and then proceed with the diagnostics and servicing of the board assembly. Notes: � Before inserting the power cord plug into the power outlet, make sure that none of the electrical parts are able to short-circuit between the workbench and the board assembly. � For the disassembly procedure of the major parts and details of the precautions to be taken, see �2.2 Removing the major parts�. � If there are wire connections from the Main board and Mechanism assemblies to the other major parts, be sure to remove them (including wires connected to the major parts) first before performing step (2). � When carrying out diagnosis and repair of the Main board assembly in the �Service position�, be sure to ground both the Main board and Mechanism assemblies. If they are improperly grounded, there may be noise on the playback picture or FDP counter display may move even when the mechanism is kept in an inoperative status. � In order to diagnose the playback or recording of the cassette tape, set the Mechanism assembly to the required mode before placing it upside down. If the mechanism mode is changed (including ejection) while it is in an upside down position the tape inside may be damaged. � For some models, the mechanism and board assemblies are attached by connectors only. When carrying out a diagnosis or repair of the boards in the �Service position�, make sure that the connectors are not disconnected. 2.5 Jig RCU mode This unit uses the following two modes for receiving remote control codes. (1) User RCU mode:Ordinary mode for use by the user. (2) Jig RCU mode: Mode for use in production and servicing. When using the Jig RCU, it is required to set the VCR to the Jig RCU mode (the mode in which codes from the Jig RCU can be received). As both of the above two modes are stored in the EEPROM, it is required to set the VCR back to the User RCU mode each time that an adjustment is made or to check that the necessary operations have been completed.These modes can be set by the operations described below. Note: � Confirm the RCU mode when exchanged parts. Since some SERVICE PARTS sets the VCR to the Jig RCU mode as initial setting.

Fig.2-5-1a User/Jig RCU mode 2.5.1 Setting the Jig RCU mode (1) Unplug the power cord plug from the power outlet. (2) Press and hold the �REC� and �PAUSE� buttons on the VCR simultaneously, while plugging the power cord plug into the power outlet. When the VCR is set to the Jig RCU mode, the symbols ( � : � ) in the time display of the FDP are turned off. (Refer to Fig.2-5-1a)
