Members Artmuzz Posted March 24, 2012 Members Share Posted March 24, 2012 About a couple of years ago the backup battery in my beloved Yamaha DX7S died. I tried to replace the battery but it was difficult as I had to de-solder the battery from the board. I tried to do this unsuccesfully by replacing with the CR2032 battery holder and new CR2032 battery but it didn't work. I was wondering if I could get away with just buying a re-writable cartridge and every time I switch the DX7S on I just select the cartridge to access the sounds I created?

Members Nightsynth Posted March 24, 2012 Members Share Posted March 24, 2012 You can buy a battery that has the circuit board attaching legs already. You will have to solder the legs to the circuit board. You can still get these from Yamaha, but you can also get them at an electronic parts store. This one should work... http://www.batterybob.com/product.asp?intProdID=303310 Link to comment Share on other sites More sharing options...
Members wildpaws Posted March 25, 2012 Members Share Posted March 25, 2012 The DX7 line (and most any synth containing a battery) will not work properly when the battery is dead. While you may store patches in a RAM cartridge, the DX7s still will not function correctly with a dead battery, there will be many other functions affected besides patch memory, such as lcd screen malfunctions, etc.Clyde Link to comment Share on other sites More sharing options...
