Been looking but so far no luck. Anyone here have a copy? Needing to replace a missing part and doing a recap and clean. Board PN is 820-0659-C. FYI, this appears to only have 25 47uf 16v caps. Does not appear to have the 100uf 6v cap.

I have a 7100/66 that is part number 820-0555-A, maybe it is close enough... what part are you missing?
I was so happy I did not melt any plastic but did not think about the fuse. I am learning with every repair.
Mine looks like a JK9B marking.
Of course the Google AI tells me:
Combined with the 100 stamp, your component is a Wickmann / Littelfuse 1.00 A polymeric PTC resettable fuse (such as the nanoSMDC100F or SMDC100F series).

What Your Markings Tell Us
- The Freemason-style symbol. Wickmann used a distinctive logo made of a "V" overlapping an upside-down "V" (forming an "A" shape) before Littelfuse acquired Wickmann. Littelfuse still uses this stamping on several surface-mount resettable fuse lines. [1]
- The 100 code. This confirms a 1.00 A hold current, meaning the fuse allows 1 amp to pass continuously and trips around 1.8 A to 2.0 A during a short or overload.
- The LI9B or JK9B text. These are factory lot and date codes used for batch tracking rather than electrical specs.

The F1 fuse. It got damaged upon using heat on a nearby capacitor. I did a lot of searching and think it is a 1 amp fuse. There are 3 fuses on the board and they are all the same.
thanks for digging. I will try something I think I found.
