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.

RF center IF 38.85MHz AF 1kHz
Modulate the AF level with a frequency 1kHz and deviation of 1.5kHz SG output level for obtaining 12dB / SINAD when injected to each point (Narrow), 3kHz (Wide). Then take from the signal generator through a 470pF coupling capacitor. output when set to -53dBm and obtain the level shown on an AF VTVM Measure the 1st Local level on a RF VTVM. when output has been adjusted to 0.63Vrms with the AF vol.
