I have an unbuilt Rev 1 QMX kit, that I? am finally seeing time ahead to build it. But am wondering, would I be better off getting a Rev 3 kit. Are there significant upgrades or differences in the current version that would make it worth getting the new kit revision?

Tnx

Hi Paul,

?

if I remember correctly for the QMX+…

?

rev 1 to rev 2 - mainly the SMPS circuit was laid down on the main board rather than plug in modules.

rev 2 to rev 3 - only the npo capacitors changed. ?Rev 2 are axial lead, rev 3 SMD that are factory installed.

?

personally, I like rev 1 best because the plug in SMPS supplies are easier to diagnose and fix if something breaks.
