Before ordering anything, I suggest you consider the following.
1) Desolder all the thermistors, MOVs and 1k ohm green body resistor.
2) Clean up all solder flux, soot, dirt, etc with a generous amount of IPA.
3) Replace the thermistors and 1k ohm green body resistor with "regular" 1k ohm resistors.
4) Leave the MOVs out of circuit. BTW, two of them look obviously damaged (blackened) and while the third (middle) looks visually okay, I wouldn't trust it and would replace it (only 65 cents).
5) Test your meter with low DC voltages and some known reference resistors.
If it all works with just "regular" 1k ohm resistors, now you can go about ordering replacements.
Since a lot of current Fluke models seemingly use the same components for input protection, I will try to write this generically for future readers.
Again, please understand that without official Fluke service manuals, BOM and schematics, that this is based on a best guess effort based on available public information and availability of parts to retail customers.
Thermistor (PTC)The thermistor should be around 1100 ohm and I believe rated at 1000V. I believe a suitable replacement is YS4020 (made by GE), but no one has it in stock?
Your replacement, B59758B0110A070, is rated for 1000V, but the resistance is 7500 ohms according to the datasheet at
http://www.epcos.com/inf/55/db/PTC_12/PTC_OC_Leaded_380V_1000V_B_B750_B774.pdfB59774B0115A070, on the other hand, is 1100 ohm resistance, but the maximum voltage is only 550V. This may be a suitable replacement if you only measure low voltages?
Varistor (MOV)The original MOVs look like they are rated for 575V. This thread has suggestions on a replacement and
at two people report it seems to work (albeit, no one has probably tested them at high voltage).
https://www.eevblog.com/forum/testgear/fixing-a-fluke-87v/Your choice, V575LA10P, is identical one to the above. Just remember, installing the MOVs might require some careful placement and possible leaning here and there to make it fit.
1k ohm resistorHere is the area where I'm not at all sure what the resistor should be. We know it is 1k ohm +/- 10%, but we don't know the exact characteristics. Does it have to be fusible like the ones used in older generation Flukes? Or has Fluke changed the specifications?
Wytnucls's suggestion that it might be a Ohmite or similar is a good one. I don't see the words flameproof or fusible in the datasheet, but again it may not matter?
Your choice, OY102KE, is 2W. However, I can't tell by size alone if it is 1W or 2W either in real life or through photos.
SummaryFor the 1k ohm resistor and MOVs, I believe you have reasonable choices.
For the thermistor (PTC), I'm not sure what ramifications the 7500 ohm will have.
PS. Did you buy this Fluke 289 in auction where you also got a Klein and Agilent meter?
