*Solved by a fellow EC user. I forgot to flatten the curve by putting a capacitor after the rectifier.
Thanks much!

DC circuit works fine.
AC circuit no bueno.
Top Left button is Set.
Top Right button is Reset.
Use the 2PST to switch between AC rectified and DC.
Why won't the circuit behave the same on both? When in AC mode, Q from the 555 won't turn off.
