This discussion was moved from another thread and might be a good one for here in the DIY section.
Many have tried numerous upgrades on the 19 XO with varying results.
Lets discuss what you have done and what the results have been.
I will start it from my very basic knowledge with a photo of the XOs built for me by member PaulC. I am sure he will join this discussion and hope to see Zilch, Dwojo, Dylan, Tom Brennan, RonSS and all you others who have interests in this area.
Here is what PaulC built for me.
Jeff Markwalts schematic was most helpful here and his input could be most valuable for this discussion.
