That is some good info about generators. Never really crossed my mind. Do you know of any manufacturers that are making newer generators, other than the inverter generators, that are putting out power clean enough to not worry about running the smaller machines off of or do they all need to be put on a scope to be checked??

Also, is there something that I can use ( an attachment of some sort) to help clean up the power on the generators that I have. I have been fortunate enough to not have had a problem yet, but I am not trying to sit around till I do. I am hooking up the Passport Plus and the Maxstar 150 STL to it. How sensitive are they?? Thanks
