I found an Iwatsu SS-5702 dual trace 20Mhz Oscilloscope in a backroom at my school and they said I could fix it. I have no clue what I am doing but I like to fix things so I thought I'd give it a shot. It was kind of taken apart and I diagnosed that 2 capacitors were torn off the board. The board itself is fine but the capacitors need to be replaced so I ordered some. Someone also ripped out the wires that run along the cathode ray and lead to some LEDS. I am pretty sure I know where the wires go from the previous solders and some old photos from this website but if anybody has the same oscilloscope and could attach a few photos of the board to this thread that would be great. I am aware the user t_glover owns one of these oscilloscopes so if it's not too much to ask, if anyone could contact him and idk ping him to this thread that would be great.

 

Welcome to AAC!

Here is the circuit diagram for the CRT section of the IWATSU SS-5702.

 

Lamboman I no longer have the SS-5702 oscilloscope. I upgraded to a SS-5706 and sold the SS-5702.
