Ikegami 1990r power supply input

Hi all. Can anyone confirm if the Ikegami 1990r has a switching power supply so I can use 120V or 240V AC input? I would prefer not to find out through trial and error. Thanks.

My 2050R2 has a large internal jumper on the power supply board that you have to set. I bet the 1990R is the same.

(Most any modern CRT is going to use a switching supply, by the way. It's still possible for voltages to be out of range for a switching supply.)

Thanks for that. I've just noticed it indicates both standard voltage ranges below the input socket and on the model info label so it must switch automatically. There was just something in the operating manual that contradicted itself which made me unsure. Cheers for the feedback.
