Re: 547 scope HV transformer problem. One practical solution.


Hi Ernesto!

The 555 is my favorite oscilloscope ever... An absolute pleasure to operate, incredible versatility (considering the range of letter & 1 series plug-in units) and the typically excellent design and construction of the 500 series! I have had one at my bench since the mid 70s and hope to keep one operational for as long as I am... 😊
