SKU: 27564-1-1-2-1 Categories: ,


Monoblock VTV Amplifier with HYPEX NCx500OEM module and VTV Custom Vacuum Tube Buffer


The NCx500OEM is a significantly more powerful module than base Purifi.  Fans of Magnepans and B&W benefit from the extra current delivered from the NCx500OEM.

Designed by Andrew Sparks of Sparkos Labs, the VTV Vacuum Tube Buffer features a direct coupled dual triode driving a four transistor Wilson current mirror.  The output of the current mirror feeds an I to V converter stage featuring the Sparkos 3602 dual discrete opamp as standard.   The board is compatible with almost any dual (or two single) opamps.  There are NO capacitors in the signal path.
