I hope I do not offend this group by asking what seems to be a question previously posted. As I stated this is my 1740 scope problem. while using it yesterday to design a PWM to control the DC motor on my wood lathe I heard a crack and then the trace disappeared. If I push the Beam Find button the trace will be about 2 cm from the top. I printed out the schematics of the previous posting and measured the input voltages to what I think is the A5 board. Correct me if I am wrong since I do not have a layout page, this assembly attaches to the big assembly that the front panel controls are connected to. I measured the voltage at the delay line input and it is 11.63V. I can control the differential by varying the Vertical Position control.
So I think everything into the A5 is OK.
My question is the correct location of the A5 assembly, just so I know I should continue looking at this PCB.
The previous poster was given such wonderful information I can only hope I will be able to solve my problem.
