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

Hi Ernesto,

I'm not surprised that the focus and astigmatism are still OK with reduced HV but don't forget that the CRT deflection factors will be affected by the HV which means the calibration will be all wrong in both the X and Y directions. Not a problem if you are just doing qualitative observations but of you want to set up the scope to do proper measurments you will need to have the correct HV and calibrate it according to the manual..

Cheers,

Morris
