I have a total of nine 6146B tubes. Some with boxes. Some are full out and some are soft. I tested this box around 8 years ago and I do not remember how many will do what. All nine for $65 to your door. Lane Ku7i _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
