Re: Avo CT160 valve testers in auction
Those battery capacity testers are good. Bought about a dozen years ago and sold all but two which I still have.
They are very simple, no processors, just big resistors and switches. What is interesting is that they will test a 2V battery by adding 6V to the battery voltage so the load transistors can actually work.
Did trace the circuit, but wonder where that went?
I would point out that they are about a 2' cube and quite a lift!
