The SuperReg Kit

The Vacuum State SuperReg is an hi-voltage regulator for use in tube preamps, phono stages, poweramp front ends, and other lowish power applications where the absolute highest sonic qualities are required.

As described in it’s own chapter in the TubePreamp CookBook, the SuperReg uses a high voltage adjustable current source feeding a high voltage adjustable shunt regulator, this unique SuperReg topology has been proven to sound considerably better than any form of series regulation when used with signal handling circuits.

--o--   It offers millivolt levels of output regulation, extremely low noise, and a wideband output impedance circa 10 milliohms.  
--o--   It can be adjusted to your exact voltage requirements between 100 and 400 VDC, and supply up to 100mA into your circuits. 400V is the maximum safe voltage limit of the components used, but much more current can be obtained if you fit bigger heatsinks.  
--o--   It needs to be powered from a DC supply between 50 & 100V higher than your chosen output voltage. Please be aware that it is only a regulator–it does not contain a power transformer, diodes or filter caps.  
--o--   The +HV and Gnd output connections are both available on opposite sides of the PCB to allow optimum star wiring into your design.  
--o--   Finished size is 122 x 88 x 25mm, mounting holes are at 108 x 76mm  
--o--   High quality 10 turn cermet trimmers allow easy adjustment of the output voltage and shunt current, and seem to sound as good as two resistors. So it’s not a sonic degrade —and it’s sure easier to set up and adjust things while it’s running than that old off–tweak–on–test–off–tweak–on jazz...  
--o--   You can use the SuperReg in hifi tube preamps, mic preamps, D/A outputs, tape recorders, poweramp driver stages, whatever—just expect a major step up in sonic qualities!  

The SuperReg kit comprises the PCB, five pages of clear instructions, and all parts—parts that fit the PCB perfectly, like trimmers with correct pin–outs and heatsinks that just click into place! It’s a real joy to build such a thing and if your time is worth anything, it’s most likely cheaper than wiring it up on some tag board with parts you have to find...
