Jerry, Sounds great...will do. Does anyone have an electronic parts list they can send me off line (I am thinking of a quicker way to order the parts is all) scott
I know this topic has been discussed to one extent or another but there has been little feedback in terms of how the perceived 'improvements' were measured. Given I was putting an order in for some p
