My dealer sent me this yesterday evening.

Here is La Marzocco's own QuickTime Movie of how the La Marzocco Mechanical Paddle Group works.

Thanks for that link, Eric. Up to now, I've assumed it was magic.

Great!

As far as I know, the manual Strada uses only the paddle to control pressure (it turns the pump as soon as it gets out of the off position). So the user have to find the spots to divert water to the exhaust and have the desired pressure. Probably it's not so easy to control (I imagine not so smooth or linear control)... A GS/3 could do this if the pump turns on right at the start of the valve opening (or lifting).

The semi-auto Strada EP is another beast...

Márcio.
