Hameg 8122 Universal Counter – teardown, repair and test

The Hameg 8122 Universal Counter is a programable counter / timer that has 3 inputs. Channel A and B from DC-150 MHz at 300 Vp-p and channel C from DC-1.6 GHz at 5 Vp-p. If you like to see other repair or teardown videos, check out this complete list!

I accidentally broke a knob off the instrument when moving and while I wanted to repair it, I might as well give a teardown of the unit. Finding a replacement part was not easy, but a cheap alternative solution was found.
