Audiophile Regulator Modules

TPR2 Micro Tracking Pre Regulator

Our objective with the TPR2, (Tracking Pre Regulator), was to produce the simplest circuit capable of supplying clean DC current to an item of audio equipment with none of the drawbacks of the LM317 circuit while maintaining ease of use and set up within a modest footprint.

We’ve exploited the feedback system of the LM317 in such a way as to eliminate as many of the limitations of this device as is possible. Using twin LM317s in a configuration where the first device is used provide DC current to the second whilst at the same time, tracking the output of the second device in a precise way.

Not content with this improved configuration, we’ve utilised a precision voltage source, impervious to fluctuations, to provide an all important stable voltage reference for the voltage regulators.

Capable of delivering over one ampere with suitable heat sinking, the TPR2 offers rejection of line borne interference by an order of magnitude resulting in a blacker audio background than can be otherwise experienced and because the reaction times to deliver transient current are faster, musical notes have that extra precision in tempo.

Even more crucial, is the ability of the TPR system to stop when the transient requirement has ended meaning less of the smearing effect sometimes noticed in heavy bass lines.·

HCR200 Regulator Modules

The new Avondale Audio HCR200 is being introduced for those listeners who would like to experience the increased detail, transparency and overall musical insight brought forward by accurate regulation of the power supply. The power supply feeds the delicate circuits that deal with the signal, stable, precise power supply rails, even under heavy transient swings, result in clearer sound reproduction.

The circuit, carefully modified by Les Wolstenholme, is largely based upon the original ‘NAPS’ regulator circuit, that used in the well-known Naim NAP250 and NAP135 power amplifiers.

Using this improved design, highest grade available components and painstaking layout we are proud to bring you the new High Current Regulator.  A few of the immediate upgrades in the layout and materials are:

  • Thick 2mm PCB substrate with gold plated pad
  • Double thickness copper track for reduced impedance
  • Tight tolerance metal film resistors
  • Premium Polystyrene capacitors
  • High grade Panasonic electrolytics
  • Significantly raised current capability
  • None intrusive, independent thermal cut off implementation

Suited to the Naim NAP250 and NAP135 though the modular design lends itself perfectly to those who would like to try them in their own build.

TPR4 Tracking Regulator – HiCap Power upgrade Version

For our new TPR4 we took the Tracking Pre Regulator system with its uniquely agile circuit and gave it a refreshing kiss of life.

Providing the circuit with a ground-plane strategy – well known in radio frequency design as being essential for stability, we then added a primary regulator system to initially control the incoming supply. Adding storage for the resulting smooth DC, we were then able to incorporate the TPR system surrounded by carefully calculated decoupling components for the ultimate in delivery of the entire audio bandwidth.

The result is one of the most accomplished regulator assemblies we’ve ever produced.

Deceptively simple (aren’t all the best designs?), this module is designed to be a drop-in item for both HiCap versions – “Chrome Bumper” and “Olive”. Simply installed by the average DIYer (two screws and 6 solder joints) it comes with a full instruction CD.

Exquisitely produced, this module will bring high-end performance to the earlier HiCap power supplies by Naim Audio, better within the reach of the enthusiast.

· Thick 2mm PCB substrate with gold plated pads
· Double thickness copper track for reduced impedance
· Tight Tolerance SMT resistors
· Extremely Precise Voltage Reference IC
· Long Life Panasonic Electrolytics and Film Capacitors
· Voltage trims positioned on PCB top edge for easy adjustment

** We also offer an alternative version of the TPR4 for upgrading the SuperCap. These are available singly for the DIY enthusiast or as a package of six regulators at a considerable cost saving.

** Note: If you want to upgrade a Naim SuperCap order our separate bundled product which requires 6 x TPR4 units, which will save you money.
