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. Lenny
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

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.

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.
