Re: 6100 HV transformer in an Amplifone HV PCB

Before you hook it up to a tube, it would be best to do a power up
test using a HV probe to verify that you get only 22KV or so. Much
more than (28KV+?) that can lead to soft x-rays...that was one other
reason I went with my raster kludge, the raster monitors had
overvoltage shutdown built in.
