This pair of Siegfried 2 Mono Amplifiers are in excellent condition. Very recently retubed at a cost of $4500 through VTL with Gold Lion KT88 Tubes. This set comes with a set of custom sized Grand Prix Audio Carbon Fiber Stands designed specifically for the VTLs.  These bases cost $6,000 per pair.  The factory crates are included along with the factory instruction manual.  Always in a dedicated music room. These amps are very heavy. local pickup preferred.   Rated 8/10 due to age.  This pair has been in my system about 7 years. DOMESTIC DELIVERY ONLY    

  • Fully balanced differential circuit – single-ended signal produces balanced signal at output

  • Re-designed fully balanced differential input and driver stages for increased signal swing, bandwidth and stability

  • Zero global Negative Feedback

  • Shorter, faster feedback loop for greater tonal control without phase shift.

  • Improved handling of loudspeaker loads for greater signal stability.

  • The amplifier is unconditionally stable, without the need for any capacitor compensation.

  • New current source for lower sonic impact in single-ended mode

  • Lower impedance output stage for improved loudspeaker control

  • Dramatically increased interleaving and coupling in the balanced VTL proprietary Reference output transformer, for wider bandwidth and zero ringing

  • Variable user-adjustable DF feedback control to vary output impedance and damping factor for optimal matching to speaker load

  • Software microprocessor controlled

    • Tetrode/Triode Switchable

    • Auto Bias, Fault Sensing

    • Current in-rush limiting

    • Standby Mute function; with reduced tube current for increased tube life

    • Fully bi-directional RS-232 control

  • 650 watts per channel in tetrode; 330 watts per channel in triode

  • Uses twelve 6550 or KT-88 tubes per monoblock

  • Adjustable precision-regulated plate and screen supplies for stable operating point; discrete regulated input and driver supply for greater signal resolution and tonality

  • Adjustable precision-regulated bias supply for greater signal resolution and noise rejection and improved isolation from mains supply variations; output operating point does not change with AC power fluctuations

  • Improved Autobias and fault sensing system to operate in fully balanced differential mode; amplifier is fully protected against output tube failure; no need for precision matching of output tubes

  • All premium Mundorf silver oil caps in signal path

  • Film bypass of power supply caps for greater HF resolution

  • Extruded aluminum front panel with luxurious, modern look – black and silver options available

  • Precision regulated B+ and screen supplies

  • Rigid construction and improved ventilation for lower operating temperature
