Yamaha Schematic Symbols

[Yamaha5000]

Yamaha has not posted a key on the schematic. Trying to understand what the symbols may mean. Notice the caps that have a circle adjacent to them, what does this circle represent? I do understand that the "J" represents 5%.

Here's a cap key from an other Yamaha Sch. It probably hasn't changed much.

I knew I had seen that key before, just couldn't put my fingers on it. Thank you for the assistance!
