Re: Covox Sound Master Reverse Engineering / Replica

Are you sure that R is 200kΩ, or might that be 2R? EDIT: Never mind. You are sure that it's 2R. And yes, the 4310R-R2R-104LF is a 100kΩ part. I'm asking because the Speech Thing uses a resistor network where 2R is 200kΩ, R is 100kΩ and the load resistor 25.5kΩ. It would have made sense for Covox to …

Re: CVX-2 : covox adapter

Speaking of the FTL Sound Adapter... That device uses a 25.5kΩ load resistor and I reckon the Speech Thing uses 25.5kΩ, as well. I'm therefore going to use 25.5kΩ for my own replicas ( new thread ). MobyGamer's measurements strongly support this assumption: Well, that was educational: CVX-1 …
