Wayne acknowledges the improvement in shielding, and all new synth boards go out with the stiffener.
AND if you had your TX synth go down and had the KRX3, I think most people would but the other in it's place, reinstating the problems if you did not modify both. Modifying only one is a dead-end tactic and booby-trapping a new owner if you ever sell it. 73, Guy.
