Very good quality original datasheet!I like this amazing website!!!!!!
 ;
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.

General description about Lead Free Solder (PbF)
The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this equipment in considering the globally environmental conservation. The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin (Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30 degrees C (86°F) more than that of the normal solder. Definition of PCB Lead Free Solder being used
The letter of �PbF� is printed either foil side or components side on the PCB using the lead free solder. (See right figure)
Service caution for repair work using Lead Free Solder (PbF) · The lead free solder has to be used when repairing the equipment for which the lead free solder is used. (Definition: The letter of �PbF� is printed on the PCB using the lead free solder.) · To put lead free solder, it should be well molten and mixed with the original lead free solder. · Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC. · Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the lead free solder. · Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30 degrees C (662±86°F). Recommended Lead Free Solder (Service Parts Route.) · The following 3 types of lead free solder are available through the service parts route. RFKZ03D01K-----------(0.3mm 100g Reel) RFKZ06D01K-----------(0.6mm 100g Reel) RFKZ10D01K-----------(1.0mm 100g Reel) Note * Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
