ECO441 was to "Lower initial frequency of 3340 to accommodate a wider range of characteristics variations on the 3340". It involves replacing Rx07 and Rx19 (217K, 1%) with 174K, 1%. 

Has anyone tried it? Is it worth the effort?

It sounds like something that is only needed if you have an oscillator that won't tune.  If all voices in your machine are working OK, don't bother.

Just curious . . . Are all of the ECO's available online somewhere?  
I've only managed to come up with some dead links.
