Since Tud1 wants to collect c.r.t. testers, I figured I would post this here. I have a Sencore CR143 tester that I purchased. I then realized that you must have the manual to operate it once I found that the instructions inside the cover were only basic and referenced the manual, so I had to buy the manual. In testing it, I found that it would not zero for some reason and without that, no test result is going to be accurate. It does power filaments or did on a couple of old sets I have, and it does give a reading which says that the meter is good.
I popped it open one day concerned with the zero function and found that a large electrolytic capacitor was warm. I opened a leg and it’s leaky as can be on a load tester. That’s not the zero problem though. At any rate, if anyone wants the thing I will let it go cheap. It is in nice condition with all cables needed to test most any c.r.t. (up to a certain generation I assume). Just PM if interested. |

Over the last 3 years, I have a B&K 445 that gives me the best read on any older CRT, I disconnected the "dynamic intensifier button" as it scares the hell out of me just thinking of actually pushing it. "Remove shorts" is a scary feature too For the previous 40 years, my Heathkit IT-5320, that works on a Beltron-style circuit. It can hit a CRT hard on rejuvenate if it needs to but Ive never trashed a cathode either
