Thanks Jimboha I have a mix of Holiday Wonderland (TrueValue?, 75) and Holiday Living (Lowes, 5x25) strings that will make up the 200 C9's. I picked up a few full wave converter boards and diodes from TomL8345 last month and assembled a few that I used on the 75 Led string. I believe all the continuation strings don't need to be rectified. I will look look out for the blob on the strings and inspect it.

Had 48 channels in my first show ever last Christmas and want to double it this year. Trying to figure if I neeeed to spend the effort on converting. Lot of learning for me. Thanks all
