The module from the A-700 will fit perfectly, but the contact spring for the speaker must be stretched a bit, and a small, thin piece of neoprene rubber on top of the battery will keep it from moving, since the caseback has that deeper dish to it.
Do you think you can help me. I want to make my Casio a700 led torquise. Change it from orange. Do you know if that’s possible. I also have a f105 and can purchase the torquise led online if needed. Do you know if one can be placed in another. Or can you do it if I paid you please. Please let me know
