Anyone with a Hitachi V680 out there?

I got a faulty hitachi V680 and the service manual plots are really hard to read.

Any good soul out there who could spare sometime and help me populate the plots?!

It just outputs vertical amplification. No horizontal sweep.

So find the Horizontal oscillator, that feeds the Deflection plates..and check it's supply voltages.
