HAMEG HM407-2 Analog / Digital Oscilloscope

My new oscilloscope ( bought second-hand at the beginning of January 2014 on a French site for 305 € including postage! ) Which now replaces my old HAMEG HM412-5 which gives some small signs of fatigue ( multi-turn potentiometersetting the sweep delay that "spits" ), but still works well ...
