Part 3 and the final part of the £5 Iwatsu SS5702 oscilloscope repair. Please enjoy comment and subcribe Thanks and Best regards Chris - AllTheGearNoIdea
Simon Spiers Yes I really should just for the practice. The Service manual looks good so I have no excuse but then again it's never going to be a TEK. Nice big screen. It's been nice to have a analog scope on the bench again. Still it's hard work not have built in counter and measurement functions.
Great job! By chance, could that e-cap next to the DIP be leaky and that's the source for the corrosion? The best way I find to insert a DIP is to go in at an angle, put one entire side in first then apply a little pressure to bend all legs at once then drop the other side...generally works flawless! :) I just got a new scope, that I'm troubleshooting, hope its as easy as yours (not...its mostly SMD's!)! ~Jack, VEG
Vintage Electronics Geek the capacitor looks and measures ok in value and ESR. I think the scope has been stored in a damp location as some of the aluminium has gone white and powdered. Yes I know the technique for inserting the IC into the socket but this one just didn't want to know I must have my tongue at the wrong angle. Good luck with your scope repair I will be watching your progress with interest. many thanks regards Chris.
Excellent job, well done Chris.
Andrewausfa a more simple job than your scope repair, still had fun.
Well, I'm going to look at my Tek 465 this weekend. That wil be fun!
