GBC POWER SUPPLIES

GBC power supplies were developed with two applications in mind. Several Blue Circle components are specifically
designed to use GBC power supplies. The HPT headphone amplifier, the Li’l703 and all FLT phono stages are some
examples. Exactly which GBC power supply is best for which component depends on the component and the level of
performance that you want to achieve. We suggest that you discuss this with us before making a decision.

The second application for GBC power supplies is to improve the performance of any solid state audio component
by replacing their internal power supply with a GBC. This can usually be accomplished by adding a GBC jack and a
minimal amount of internal circuitry. This is true for Blue Circle products, primarily phono stages and DACs, as well
as those produced by other manufacturers. Even devices that use “wall-wart” power supplies, like laptops, can benefit
from replacing them with a GBC.

GBC power supplies are housed in ABS tubing to keep costs down. In some rare cases, where heat-sinking is an issue,
a metal chassis may be required. Pricing below is for GBS power supplies in ABS housing only. If a metal chassis is
required we will have to give you a quote.

POWER SUPPLIES AND UPGRADES

THE KQ POWER BOX  
          
The KQ Power Box is a power supply upgrade. It is designed to improve the performance of any amp, preamp, DAC,

or any other audio component. Blue Circle has been at the forefront of power supply research for many years.

The improvement in performance resulting from a KQ upgrade, especially for components not manufactured by

Blue Circle, can be quite significant.



Most Blue Circle components can accept a KQ upgrade with only minor modifications. These include the installation

of a KQ jack and additional soft-start circuitry. Components not manufactured by Blue Circle can also be modified to

accept a Power Box upgrade. Depending on the application and the size of the upgrade, the Power Box may require

a separate chassis, or in some cases, the upgrade can be done internally. The actual cost of the KQ upgrade will

depend on the component it is being designed for and how significant an upgrade the customer wants. Once we have

worked out the design parameters with you, we can give you a price.
