I'm working on repairing/diagnosing my oscilloscope, since Im dealing with the CRT power supply, the service manual recommends that I use an isolation transformer. I dont have a plain transformer, but I do have a 0-140V varac.
Is it ok to use this? and there is no ground pin on the varac itself, can I operate the scope without the ground connected?
I was thinking about just running a wire from the ground on the scope to the ground on the wall outlet. I figure it's better than running it without a ground, but I dont know if that will unisolate the scope.
I'm working on it as I'm typing this, so please respond ASAP if you can help.
Thanks.
