Yep, the same goes for the Classic. Thats a very nice pictorial guide.
Apart from the difference in the length of the steam arm, the hole in the steaming tip is larger than that of the Gaggia, so there is more steam, but the boiler struggles to keep up. The one thing I noticed is that if you wait for the element to turn off before you steam, the steam pressure drops dramatically and quite rapidly. I used to start steaming maybe 5 seconds before the thermostat clicked off and got a very nice and nearly constant jet of steam that can easily foam enough milk for 2 cappuccinos. This means the elements are full on during the steaming.
I used the digital temperature display on the PID controller to judge the correct point to start steaming. The element would switch off at around 165 deg C so I would start steaming at 150 deg C to prevent this. The elements are just shy of maintaining the boiler temperature whilst steaming, so are able to keep the pressure up for quite some time.
The thermostat hysteresis on my machine was over 30 degrees (on at around 130 and off at around 165), so there is a huge pressure fluctuation if the elements are allowed to switch off.
If you dont have a digital thermometer, youd need to time it. (30 to 40 sec from hitting the steam switch).
