Come on man! Use a lithium ion battery with a DC to DC converter. I know you can do it.
Yeah, thumbnail sized DCDC converters are inexpensive and reliable.
I got this more as a memento of my time selling my soul to Ma. I'll put it with my collection of other bell stuff.
Yes, but I also have a $65 oscilloscope meter that does everything this one does to a better degree of accuracy.
I got my oscilloscope free from an old engineer that left it out in the weather for a year. It still fired right up and continues to work great 6-7 years later
Some of those old ones were bricks. The one I'm currently using is a portable scope meter, but I still have a couple of CRT units around.
