...the bottom open circle and the arrow indicates that is the articulating contact in the relay switch correct? The top open circle is everything else and is the stationary contact?

No, in schematic arcana, the arrow is always the stationary contact and the moving contact is always what the coil "pulls" on.

GREAT!!! Thank you for that piece of knowledge! I think I have the relay hooked up correctly. The stationary contact has the tied together pin #8s from both 5U4s and the yellow lead from the small secondary coil soldered to it as well. I'm going to double check the wiring in the rectifier circuit then move on to checking the moving contact leads and how they trace out.
