I tried that, but it didn't work. When I took it apart there was quite a bit of corrosion on the PCB which was likely causing some other problems as well. I just got a good working one for about $70 and stuck it in it's place. I'll just chalk it up to parts or if I find another non-working one I'll combine the two into another good working one.
I am in Vero Beach, FL (East Central Florida on the coast) Last one I picked up about a month ago was just refurbished and got it for $76 bucks... It was used to replace a worn out Maka.
I might have a 2501 to throw in its place... Do you know off the top of your head if I can just swap out the faceplates on those and be good to go?
