The symbols will be on the bottom of the combo filter cap. It just tells you which lead comes from where. Most filter caps are 40/ 60 or 80 for example so it matters what connects to where. In your case, it doesn’t matter as they both (the triangle and Box) are the same value (10 MFD) You will see this system of identifying the leads on other filter caps quite often on other radios.

Good luck, Gary
