Kikusui oscilloscope 2ch cos 5020 1993 test repair teardown

this one had a few funny errors, ch1 attenuator 3 settings dead, easy to figure out using schematic, and sweep error at x10mag, all is now solved and scope is tip top, can show and trig up to 50MHz.
(at 27 mins where is curve is most crasy)
