In order to look at 12v-120v dc-ac inverter waveforms, (recent post), I bought the above dual beam 'scope over EBay and find the only problem seems to be a bad CH1 attenuator (trace vertical position "all over the map" if rotary switch touched). Anyone with experience of this 'scope? Dick

Thanks for the encouragement Wolfgang, It looks pretty tight in there as though I would have to pull the preamp circuit board out for access. I only paid $20.50 USD+ shipping for the 'scope so am reluctant to send it to Kikusui in Portland for repair. I used CH2 to display and capture the output waveforms of three different dc-ac "modified sine wave" inverters using a digital camera. Interestingly they were quite different one from the other two though they had very similar rms values of ~121v. I constructed piecewise linear descriptions of these waves to check my LPF using 5Spice. I am trying to get a 19.2v drill battery charger to run off one of the inverters. Regards, Dick
Hi Dick,

I have a '5040 which served me well over the past 15 years.
It should be too difficult to repair that. I think its only a loose connector or a bad contact on the rotary switch.
Good luck, Wolfgang
