I both the Sencore CR 133 and CR 143 CRT testers. I need to get rid of one of them. Condition of the two is comparable. Which one do I toss? Why? I know little about these. Thank you in advance.

Didn't you make a thread about this earlier? If so making a second one is a BAD thing...You should have bumped the first.

Please don't throw one away, let someone who needs one have a chance to buy it.

I've never used either, but if I had to decide off hand I'd go for the 143. Higher number is usually newer, and newer is usually better...YMMV.

Yep. Test equipment such as this is one of the only things that actually got BETTER with time. The Sencore 133 and 143 are both good machines, but the rejuvenate functions on older testers is quite potent, especially on old B&K's. My daily use testers are a B&K 445, and B&K 470. I only use the 445 to test.
