Yes, you are correct... There should be another bridge rectifier between the
transformer and the regulator. Also notice the positive and negative
connections on the bridge that is there are reversed.

I'm working on a new circuit now and I'll post it along with these fixes
soon.

I appreciate you looking at it.

Thanks,
Cameron
