304tl - Finished!!!

Finished - Eimac 304tl Single Ended Mono Amps

They have a certain appeal

Construction was as modular as possible

Safety is critical in these amps as there is 1,100 volts on the heat dissipating plate cap

They also put out considerable heat.  Like sitting by a fireplace!

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.
