A complete Plasma Tube System built into a metal case.

This researcher used a metal case for his system. He also sends DC power through the coaxial cable to the cooling fan for the LC31 coupler.
Front view of the system enclosure. Rear view of the system enclosure. This is the heart of the plasma tube system. Power supplies, SPA5 amplifier and controls. (View 1) This is the heart of the plasma tube system. Power supplies, SPA5 amplifier and controls. (View 2) Seen on the right side of the SPA5 is the Spectrotek DCT-1 that inserts DC fan power into the coaxial cable.
Attached to the LC31BST coupler is the Spectrotek DCT-1 that removes the DC fan power from the coaxial cable. The plasma tube holder with the LC31BAT coupler and cooling fan. The plasma tube holder is placed on the top of the amplifier enclosure. The completed system in use.
