High Voltage
                  Tubes
                        Most Bare-Rife tubes that have internal electrodes may also 
                    be used in the high voltage PMR/EMEM type systems. Typically 
                    however, the high voltage systems cannot bring the plasma 
                    to the same state of excitement expected of Bare-Rife systems 
                    and we typically scale down the size of the tube for better 
                    performance. Phanatron tubes, reportedly tend to be difficult 
                    or require more drive than the newer modern efficient E-Gas 
                    tubes.
                  Bubble Tubes
                   Bubble tubes have become the norm for most rife work. Especially 
                    true in Bare-Rife (RF) excited configurations, the extra gas 
                    volume as well as a convenient contact point for hand placement 
                    in contact applications.

                  Specialty Shapes
                   Actually … to refer to these as “specialty” 
                    may be a disservice as these are typically very fine “utility” 
                    performers.
