I just went thought this process and the new KRX3 comes with the new synth. I had to pick up a new synth to replace the old one in the main receiver as they have to match.
It only took 12 hours to do it all including redoing the filters in the receiver because I did not read the manual close enough and my mis-understanding of the implication of “optional steps” regarding the connection to the KAT3 tuner for the KRX3. Hence, I am the cautionary tale about not reading the manual :) But, I will say that doing this work makes me sorry I did not buy the kits for both K3s--that would be the plural of K3 versus a K3S :). It was GREAT FUN to install the sub receiver. I really enjoyed the fact that when someone was explaining routing the TMP cables, and installing the new pre-amp, I could see the exact parts and how they fit together. It made something abstract quite real and I like that. Regards, Tom Schaefer, NY4I 727-437-2771 P.S. Drowning in email?
