VTV AMPLIFIER Stereo HYPEX NC500OEM Amplifier with VTV Vacuum Tube Buffer


SKU: 27564-1-2 Categories: ,


NEW Stereo VTV Amplifier with HYPEX NC500OEM modules and VTV Custom Vacuum Tube Buffers.

The NC500OEM is significantly more powerful than the Purifi 1ET400A.  The HYPEX NC500OEM is an excellent option for B&W and Magnepan owners.

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 dual discrete opamp.  The board is compatible with almost any dual (or two single) opamps we offer…contact us for substitution.  There are NO capacitors in the signal path.
