I have power cables made by Terry and Wolf (all of course do excellent work) but I found that a Lectrosonic power cable is a simple ( and inexpensive) emergency backup for a Decimator if it still has the original power connector. Many sound guys have these cables stuffed away and never used. It has a Hirose connector and the Lectros use the same slide in power connector that comes on the Decimator. I know it's used on the older 190 and 195 Lectros, not sure about their newer models. After I confirmed it worked, the audio guy gave me the cable saying he had plenty and rarely used them. Bought another on Ebay for $25.
I'll eventually get mine refitted with better connector, but for now I have a good backup.
