Midgrade? Might be an argument for low peripheral.

I'm guessing F1 and the 3A(mp?) means it's a fuse but not sure

I was thinking fuse too but the gold on the ends is what has me confused.

F1 is a fuse. 100% sure. It's just a quality surface mount fuse. Yes. Those are gold plated end caps on the fuse. And yes. It is 3 amp rating.
I don't see me grading the board.

Nano fuses! Those gold caps are highly gold plated or silver bearing. This is one item I actually collect and refine myself.

If you can gather enough in quantity, BS will buy these at a specific rating. You can also find a jeweler.

These fuses and gold capped in-line resistors, have these style of caps on them. You have to remove the resistors cover/plastic/epoxy or enamel/paint to see the gold caps. (rare though) Mostly on the carbon composition types(fixed resistors).

Always check ceramic boxed or ceramic wire wound resistors too. They do sometimes have heavy gold pins or the actual contact point itself; that's suppose to break connection on overload, is highly gold plated.

Spence1015. What are your comments on these two components? I am showing the original condition. And then when I cut them open. Those are ceramic hybrids. I value your opinion.
