[NJARC] Old Battery Question

Hi Guys-
As I mentioned, the 75% seemed suspect to me- my DVM drives me nuts: I know the VTVM in my Precision set tester is reasonably accurate, enough for my needs. The set tester I am working on is one where it plugs into the tube socket, and the tube goes in the other end, and you get reading on all the voltages & resistances, etc for the tube socket.
I would enjoy working with newer test equipment. I haven't any much beyond the oscilloscope, but even that is old. I can't afford the newer stuff, and am quite happy getting the older stuff to work. It is less complicated, and the digital "True RMS" I have just annoys the daylights out of me- I like a readout which stabilizes- not spends all its time wandering about.
Anyway, I'm building a battery pack, actually two, and hope to have the set in operation tonight sometime. Then I can finish building a test adapter(the set had all but one of its adapters- the one for octal. Figures. However, it has a standard 7 pin base, and I had one on a tube which was suspect, so I carefully removed it, and am mating it to an octal socket, having devined the proper pin-out for the octal adapter, based on the socket which clips on the end to go into the set. Once it is all together, I can probably get some reasonable readings on what the BC-348 is doing. Sorry it seems like I do things the hard way, but I have to work with what I have.
