Service Manual for Hitachi V-203f Oscilloscope needed!!

[overtone85]

Hi, this is my first post.

I just picked up a Hitachi V-203F Oscilloscope for £50 here in UK, but it's not calibrated (i should have known better ). I did find an unsold ebay listing for the service manual. The seller says he still has it but after the first exchange of messages he's not replying anymore.

Does anybody have the service manual for this model, and is willing to scan it and provide a PDF? I can also make a small paypal donation if you can do that.

Cheers

Thanks but, sorry, that is the Operation Manual.

I need the Service Manual that contains the instructions for the calibration of the scope.

Yey of little faith... 

It is an old school operations AND service manual.. There is schematic and calibration procedure inside... 

It is how it used to be long time ago...

I noticed that section of the Operation manual, but it's only showing user adjustments for astigmatism, gain and Volt/Div balance.
It does not include the adjustments for things like:
Power supply voltages
CRT high voltages
Minimum and maximum brightness
Retrace brightness
Vertical Transient response

and a bunch of other things, just like the procedure in this video

Yes, you're right, it doesn't have that.. Sorry.

Hope someone will be able to share it with you...
