Otaining replacement resistors is not a problem. The problem is that the
guy who started stripping it did not (obviously) document what he was
ripping apart. So I have no idea what resistors were removed, or how they
were connected. This thing is built on tagboards, the resistors could
have gone in several different orientations. And wires were cut to get to
bits of the instrument :-(
No, I don't have a servive manual, or a scheamtic. I doubt I'll ever get
an official one. The only possible way forward seems to be to work out
what I have and work out what would most likely have been added to make
it work.
[3] It was given to my school (the worst thing to
do to any piece of
historic equipment IMHO). It didn't work, the teachers couldn't see the
point of it, and alas before I got to hear of it, some idiot had started
raiding it for the precision resistors. I realised what it was before too
much damage had been done, and managed ot get them to give it to me. But
it's going to be a lot of work to get going again.
I suspect the resistors will not be hard to replace, as resistor quality
has gone up over the years. What is sad is the loss of
well designed
equipment since the puter era.
Agreed. I am not sure what you mean by 'puter era', but there were a
number of post-war measuring instruments, etc, that while not directely
computer-related (or even digital) are certainly worth preserving.
