I have a Simpson 260 series 8 meter with two burned resistors. Simpson
will not provide a schematic for these anymore citing some BS safety
requirement. I would have to send it to them for repair. Of course I
would! Does anyone have this model who could please look at the
section of the board I would identify in question and tell me what
resistors are in those positions? I would sincerely appreciate any
help with this. Thanks, Lenny

I've been there but there's no schematics for the series 8 though.

I'm not familiar with these meters but there is the schematic for
Simpson 260 Series 8 - VOM 260-8xi 1969 Edition

Is that not the same?

You should download the 260-8xi schematic from
http://simpson260.com/downloads/simpson_260-8xi_schematic.pdf. Simpson uses
the same basic design for a meter, changing features for the different
models in a series. The 260-8xi schematic should cover the basic series 8
model as well. Just ignore any features in the 8xi that aren't in the basic
series 8.

Cheers!!

The 8xi is a totally different design. Although it still uses a 50uA
movement and would likely have some resistor values etc in common, the 8xi
has several additional ranges, does not have the 5kv range and is a rather
different physical form factor. These are just the differences I can name
from memory.

The series 8 bakelite model should probably be much closer to the series 7
in design, I would think.

There are quite a few Simpson manuals here:
ftp://bama.sbc.edu/downloads/simpson/

Unfortunately the following is only a user manual:
ftp://bama.sbc.edu/downloads/simpson/260-8/

FWIW, I notice that the 260 Series 5 has resistor strings that are
similar to those in the 260-8xi.

If you could tell us the values of other resistors in the same string,
then perhaps we could work out the values of the burnt ones.

I've written to Simpson and included a diagram of the board which
shows the burnt resistors. We'll see if they respond favorably. I'll
let you know. Thanks, Lenny.
