Kikusui oscilloscope 3ch type 5060A 1985 blanking issue

cool to see it is a 3ch scope, yes it can show 3 traces at the same time, dual timebase, and a nice long delay line, but sadly I had to give up after 4 days trying to solve the blanking issue, time is up, it go on pause to another day, back on stock..

I use auto generated subs, I go through them myself, but i am far from perfect at finding all errors, so if you find errors worth fixing, please comment (or PM) with the TIME in the video you saw the error, i will be happy to fix it. This also applies to the Danish version.
