I work mainly on vintage tube radios and guitar amps. I recently got an oscilloscope for my bench. I understand that in order to protect the oscilloscope, it should be plugged into an isolation transformer. I am searching for an appropriate isolation transformer, but so far I've had no luck. It seems like on all the products that I look at on Amazon or other supply sites, someone comments that that product is not truly isolated and that you need to make a mod to it. I'd prefer to buy something that I don't have to mod. Anyone have any recommendations for me?
