Restoring an HP 150A Oscilloscope (Part 4) – Victory!

It was a brutally long repair, but we got there! I won’t spoil too much, but in our diagnosing process we traveled all over the scope, replacing a litany of parts, but in this episode, we finally crack the code and emerge victorious. It’s a good day indeed!
