Hi 
any hands on experiences detail that might be useful if I do it myself when the kit arrives.  Thanks

John,

Yes, there are lockwashers behind the board - when removing the old
synth, do not initially remove the screws completely - loosen them until
they are almost out, then tilt the board toward the rear and push the
lockwashers up against the old synth board.
Now you can fully remove the screws without dropping the lockwashers
(they will stay on the screws if you are careful)

When I upgraded my synths, the big problem was getting the TMP
connectors correctly replugged. The manual said where to run
them, but getting them reliably plugged in was my problem. You
need to get the center conductor to slip smoothly into the
socket. Then the rest of the connector will go in easily.

Hi Don
I was thinking of you when making this inquiry.  Thank you!  
I’m also changing K3 to other changes: usb io, plus adding the 2 meter and GPS boards aimed at the digital mode use.  
Awaiting last K3 update production boards to arrive in June.  
Again thanks for tip on synthesizer board washers when removing the old board.
