Tweak for Rogue Preamp Owners


Mark O. contacted me and said they are now drilling a hole in the outboard power supplies and are providing "corks" for the hole.Fill the power suppy with sand and it makes an already quiet tube preamp into a super quiet tube preamp.Mark said it reduces floor and tube noise.You guys that have a "older" Rogue can do this your self.Just make sure you remove the cover first so you dont drill through something kind of important!!! Contact Mark if you need some assistance.I havent done mine yet but will soon.

My only concern with a "tweak" or "mod" like this would be heat dissipation. If there are any parts that are running near their rated amount of power dissipation, doing something like this could cause premature parts failure due to excessive heat build-up. The sand would act as an insulator minimizing the natural convection of heat away from the components. Hopefully, the designers / manufacturer has taken this into account and is not just offering the "latest / greatest" mod just to keep up with the "in" crowd of "tweakaholics". This is not to mention that all sand should be thoroughly sifted and dried before putting into ANYTHING. Don't trust pre-packaged "children's sand" as being clean, sterile or dry. I would hate for someone to find out the hard & expensive way that the sand was moist or had conductive contaminants in it and that their gear shorted out from doing something of this nature. Sean >
David, i simply mentioned those things as some people might take for granted that this "tweak" might work on other gear and do it without considering some of the existing consequences. On the same note, some folks are "trusting" and assume that "store bought" sand would have already been filtered and should be dry from sitting inside the store. Needless to say, foreign particles DO make it into just about anything that is mass produced and pre-packaged and moisture / condensation can collect within sealed plastic bags. Sorry if you took offense, but i was just trying to cover all of our "assets" : ) Sean >
