That's great Max. Good job. They are nice little scopes.

Good news! I replaced the PSU filter caps, and I noticed the 33uF/160V on the 100V PSU output, and it's all good!

Looking at the base of this capacitor, it was quite obvious that it was the failed one, the black epoxy has come off near one of the legs and when I attempt to measure it's capacitance on my (cheap) multi-meter it reads almost 0nF. In fact, I think the black epoxy had come off under such pressure that it pushed the cap up, and crack the solder joint!

Look at the difference nice new caps have !

Thanks very much for your help, Tom, very much appreciated!
