I think it was me that bought ReDrum's. I also have one other but I have never so much as tried to turn one on. It is still down my list of projects. I need to finish my A3000T project first. My A2000 Bomac Tower project 2nd, and then get a couple of the 4 non-working A4000T's I have working. I know very little about Rejuvinators. The second one I had was in a homemade tower project which I took apart. I plan on putting that Rejuvinator in a standard case.
