Hughes & Kettner RM-40 Rackmount Kit

The RM-40 rack mounts are screwed to the side of your TubeMeister Deluxe 40 & GrandMeister Deluxe 40 to turn your amp into a ready-made (4 HU) 19" rack unit. Note The hot tone of tubes needs cooling! We recommend building your amp into a rack only if you have sufficient cooling and ventilation. Commercially available 19" cooling fans from the world of home computing are well suited to this purpose, for example the PROCOOL HK640B, which was custom designed for Hughes & Kettner.
