I just purchased a like new Whites Goldmaster V/sat. Its a beautiful machine, and looks as though it has never been used. My question is this. It comes with a 6 by 10 gold master coil. It looks like the stock coil. However it does not say if its a DD. If it doesn't say that, am I to assume its not a DD. Even the instuction manual make no referance to this. I would like to have a DD coil for this machine, and I do see that whites still makes some nice ones for it. Any help will be greatly appreciated. Kidd
