Yes, I had it switched to AC coupling. By "zoom" I meant the volts/div was at the lowest setting. 2mV/div I believe.
So for looking at the AC component riding on DC you use AC coupling at the vertical input (blocking the DC level). Then you increase the vertical gain allowing you to see the AC. That is how we look at ripple. Did you ever see the sine wave fro your transformer before the rectification? The scope will display the actual peak to peak value of the sine wave.
