Beast Mode II
Just wrapping up with the first Beast Mode II Power Supply Unit. No expense has been spared in creating this. It is the biggest, most badass power supply I have ever created. It has been said that bigger is not necessarily better. However, in this particular situation bigger is absolutely better. The Beast Mode II has been designed to supply ultra low noise, high current power to four Trinity channel strips. It has separate power transformers for the B+ power, phantom power, and tube filament supplies. The big blue transformer supplies the B+ and also has a 6v tapoff, which powers the LED circuitry. Inside is a massive power filter choke, a pair of low noise toroidal transformers, and the electronics necessary for regulation of each power supply within the Beast Mode II. On the back side can be seen the can caps, a thermal relay tube, a pair of voltage regulator tubes, the heatsink associated with the tube filament regulator supply, and the octal power sockets used to connect power to each channel of Trinity.
Its definitely a strange hybrid, but it performs unbelievably well. Silicon diodes were used for all power rectification (B+, filament supply, phantom power, LED power supply). A very expensive military-grade solid-state voltage regulator is used to perfectly regulate the DC voltage for the vacuum tube heater filaments in order to achieve supremely low noise. The square black heatsink can be seen on the back side of the Beast Mode II. The two large vacuum tubes on the back are actually not vacuum tubes. They are filled with Xenon gas and are used to regulate the B+ voltage - in conjunction with capacitors & a filter choke. The resulting B+ power is perfectly free from ripple or voltage swing. The small tube on the back is actually a thermal relay vacuum tube. It controls an automated start up sequence that's much like a standby switch on a guitar amp. This standby switch automatically flips on 60 seconds after the power switch is turned on. The phantom power section offers a dedicated power supply for each channel, with each one being regulated to provide up to 2 amps of direct current at exactly 46.6 volts. The LED power section is the only non-regulated supply in the Beast Mode II. It provides 4 amps (way overkill) of direct current at 6 volts to power the LED lights on each connected channel of Trinity.
