I started the build process with the most important element first. The power supply. The power supply is responsible for far more than just mere power. Its generally the largest source of noise, a major source of headroom, and a significant factor in the origins of punchiness. Therefore, in order to make a great power supply, great care and skill has to go into its design. Ladies, Gentlemen, and Rough Folk, I'm proud to share with you the first production model of The Beast Mode Power Supply Unit. Please forgive my novice photography at the bench (unofficial photos).
The Beat Mode PSU is the power supply for Trinity (October 2015) and can power up to two Trinity units. It will also very likely continue on to use for future products. This is a hybrid sort of power supply since it has both solid state and vacuum tube technology onboard. The vacuum tube seen in the above photo is actually a thermal relay tube, which controls a time-delayed soft-start for the tubes on any Trinity connected. You can think of this as an automatic standby switch. Also seen in the photo is large heat sink. This is for cooling the linear voltage regulator below it. That regulator is related to the heater filament power for Trinity's vacuum tubes. It keeps it at a very stable DC voltage for superior low noise performance. The massive blue power transformer is one of 3 onboard. The other two transformers are internally mounted.
This thing is really over the top in such a good way. All point to point wired. Thick high quality wiring for maximum current delivery. Big wattage resistors for low thermal noise. Low ESR, long-life electrolytic caps. Separate power transformers for each section of power: B+, Filaments, Phantom Power.
The Beast Mode PSU is a heavy weight contender (it weighs a lot), but it is not the entire power supply for Trinity. Onboard each Trinity is the voltage regulation circuitry for the B+ section of the power supply associated with that particular Trinity Unit, so that each connected Trinity will have its own separate B+ supply. The regulators onboard Trinity are not solid state, they are inert gas VR tubes. In fact, nothing onboard Trinity is solid state. That definitely means the audio path is 100% pure vacuum tube heaven. And, ultra-low noise, of course.
