buy a gs3 if you dont know the nostalgia of a machine like this BTW the gs3's just came down in price and you can have your paddle.<br />
<br />
barry nice machine might have jumped on it but i just got a 2010 STI im waiting for someone that has a 2-3grp that might trade for my vintage victoria arduino.<br />

Barry,<br />
<br />
That's a magnificent machine and a magnificent piece of work on your part. I would consider buying it to display as a "before and after" with my GS/3, but it would only confirm what friends and family think about my sanity.<br />
<br />
I hope you won't mind that I took the liberty of saving your wonderful photos for personal reference.<br />
<br />
Have you considered offering this piece of history to Enrico Maltoni?<br />

<br />
For those of you interested in provenance, this machine originally belonged to David Schomer of Espresso Vivace in Seattle and was used in his home kitchen after he developed the control parameters for his prototype PID-governed Linea. That original Linea still chugs out superb shots for personnel who work in David's roaster warehouse. The control logic and design modifications of that Linea were ultimately migrated to Dave's production machines in his cafes, as well as to this little performer which was to live at his home. This GS-1 chugs out superb shots just like its larger sibling.<br />

I don't know what the interest is for this cool machine, but If i could convert it to a paddel group for a reasonable price I could come up with $3000. Where is it located?<br />

Hi Terry and Chris,<br />
There is at least a difference that involves a group casting feature in the manual neck to allow the placement down through the neck of a rod to actuate the microswitch located below which controls the pump.<br />
<br />
Terry, perhaps you know if there is also a difference in the bottom of the neck casting where the valve cup exits through the casting. In the manual group there is a groove there for an o-ring that seals the nipple at the base of the cup at the bottom of the valve body…
Hi Terry and Chris,<br />

<br />
Terry, perhaps you know if there is also a difference in the bottom of the neck casting where the valve cup exits through the casting. In the manual group there is a groove there for an o-ring that seals the nipple at the base of the cup at the bottom of the valve body where the cup makes its exit through the neck casting to supply flow to the diffusion block. (This o-ring likes to leak dripwise after it gets hard as rock over time, btw.)<br />
<br />
On Terry's site you can view the exploded diagram of a manual group valve body:<br />
<br />
<a href="http://www.espressoparts.com/GSManualGroup" target="_blank">http://www.espressoparts.com/GSManualGroup</a><br />
<br />
<br />
I'm not certain that the solenoid version is the same there. I have not had my solenoid group apart in that region.<br />
<br />
Look at this cutaway to see that the feed tube of a solenoid group joins an assembly that threads down into the neck casting above where the diffusion block threads up into its hole:<br />
<br />
<a href="http://www.home-barista.com/espresso-machines/cutaway-of-la-marzocco-saturated-grouphead-t700.html" target="_blank">http://www.home-barista.com/espresso-machines/cutaway-of-la-marzocco-saturated-grouphead-t700.html</a><br />
<br />
So, it may be the case that a manual neck is required turn a solenoid group into a manual group. Or perhaps a part could be machined to thread in and accomodate the o-ring requirement as necessary.<br />
<br />
If I'm wrong about this, I imagine that the switching for the pump in a conversion could be cleverly accomplished with a microswitch mounted on top of the group rather than below the group...no need for the rod business. Cyncras have their switches up there in direct contact with paddle cams for actuation :>)<br />
<br />
In any case, I have a manual neck casting and access to a valve assembly and a Paddle, so conversion to Paddle is completely within reason.<br />
