The Real  Tubes Electronic Crossover.



Flagship grade tubes electronic crossover.

The mono block with external power supply , 4 unit design.

They use T-LC type design crossover , T-LC Type is Line output transformer drive the LC network for low-pass and high-pass filter. This type is lowest loss of fine detail design. Also get the Linear-Phase.

The crossover frequencies and octave change by LC crossover network card.

The Real electronic crossover use 5687WA/B with Tango line input transformer for Class A input stage to drive the LC network.  The 5687WA/B and 12B4 drive Tango line output transformer construct Class A output stage .

 

The Real 's application of a highly efficient solid-state voltage regulator with 6X4 Tube for current regulator and Tango choke in the HVB+ power supply . Also it use the external power supply get highest S/N.
