Building the 304tl

304tl

The tube cage is one of the most important aspects of this design. Without a safe cage, the amp is completely impractical with over 1000 volts on the heat sink plate connector. This cage uses custom cut glass and aluminum L brackets for construction. Sides and top use a metal screen from the big bin at Lowes.

Sides and top

These amps cover 4 chassis, each weighing over 50 pounds.  Being modular helped with construction but care had to be taken to ensure that the connections were safe and flexible.
