Re: Tektronix 2465B Square wave noise on active readout. #photo-notice

Sorry if It's obvious, but is it normal to have around 42 ohms across the 5 & -5 volt rails and ground?
I was just checking continuity on the damaged area around U650, and the ceramic caps in the 5v power distribution, (in particular C675) appear as ~42R, with the resistance going up as I measure caps further away in the same rail. Also, pins 12 and 5 of J119 give out around 42R.
