Hameg HM312-8 Vintage Oscilloscope Teardown and quick Fix

A little look inside my late seventies/early eighties vintage Hameg HM 312-8 oscilloscope. Fixing a little problem by cleaning some contacts. The Android function generator app I used is made by Keuwlsoft. They also make a bunch of other apps that look interesting. (I didn't test anything else yet, though.)
