The DynaGrid Rectifier

A superior tube rectifier

DynaGrid is the holy grail of tube rectifiers.  

It works by replacing your 5U4 or compatible rectifier tube with high current ultra fast recovery diodes that are buffered by large silicon resistors which then feed an 845 triode tube.  The 845 is a series pass-thru device that via its control grid governs the voltage drop and sag characteristics in real time.  It duplicates the operation of your stock rectifier tube in preamps or amplifiers alike but has superior sonics and performance, -- and it never wears out.
