Usually the current rating is the RMS current. With a capacitive input supply the RMS current can be many times the output current. 3:1 is common.

With a good choke input supply, the RMS current and DC output current are essentially the same.

Play safe and play longer! Don't be an "OUCH!" casualty.
Unplug it, discharge it and measure it (twice) before you touch it.

  Thanks
  I will need to put before a choke around 1uF to bring up voltage a little. So it won't be "pure choke" but close enough.

    Make sure you use Ultra Fast Diodes if you aren't using a tube rectifier.

      I'll use damper diodes.
      Thanks a bunch!, L
