Vintage Phase Linear Audio Upgrade Products

White Oak Audio Design standard products are professional grade upgrade products for vintage electronic equipment with a specialization in early Phase Linear amplifiers in their golden years when Bob Carver was still at the company.  Our Upgrade Products for the Phase Linear 400 Series 1 and Phase Linear 700B amplifiers are LED light boards to replace the failure prone and heat producing incandescent originals.  White Oak has set the standard for quality and is the premier LED light board upgrade available on the web.  White Oak Audio offers an innovative power supply bulk capacitor upgrade kit for the PL 400.  This upgrade will triple the original power supply value and increase the voltage rating of the capacitors to give your PL 400 more bass punch and sound quality than the original. 

White Oak Audio Design meticulously engineers each of its kits to be a direct drop in replacement for the original parts designed by Phase Linear.  This allows the Phase Linear collector to upgrade his equipment while not destroying the original value of the equipment by requiring any irreversable modifications to the base product.

White Oak Audio also offers several upgrades for the Radio Shack Realistic TM-1001 AM/FM tuner.  These upgrades consist of LED light board illumination upgrades as well as power supply and final audio output improvements to enhance the performance of an already great performer.

The White Oak Audio Design website hosts a document vault with many important reference documents for vintage audio equipment and our upgrade kits.  Please access our Documentation page to view these resources.

Our audio upgrade products are available for sale on Ebay, Audio Asylum, Phoenix Audio Tape Company, Phoenix Audio Community Forums as well as on our own White Oak Audio eStore

Honda and Acura Automotive Products

White Oak has developed an innovative and reliable piggyback ECU controller for Honda and Acura automobiles to increase the performance of normally aspirated as well as supercharged and turbocharged engines.  This Multi Purpose Fuel Injector (MPFI) controller when coupled with the Windows based tuning utility developed by White Oak makes it easy to increase the engine output.  White Oak also has developed what has become the gold standard "boost mask" MAP clamp for supercharged and turbocharged engines.  This allows the use of boost pressure without modifications to the vehicle ECU.  The "boost mask" is the first product that White Oak developed and manufactured and forms the genesis of the company.
