Key Features & Architecture ::
Circuitry & Design::
Class-A Tube Stages: Eight 6072 dual triodes optimized for high headroom.
Transformer coupled: Hand selected and custom input/output transformers and passive LC inductors.
True Stereo Control: Single set of high-precision controls simultaneously adjusts both channels.
Precision Switches: High-quality silver-contact switches for repeatable recall.
Audio Performance::
Frequency Response: Flat within ± 0.5 text{ dB} from 20 text{ cps} to 20 text{ kc}.
Wide Bandwidth: -3 text{ dB} down at 0.5 text{ cps} and 80 text{ kc}.
Low Distortion: THD + Noise < 0.10\% across full audio spectrum.
Signal-to-Noise: 82 text{ dB} minimum S/N ratio.
Independent EQ Section Controls
Control Frequencies / Bandwidth Gain / Range
Low Cut 30, 40, 100, or 400 Hz 0 to -10 dB shelving (1 dB steps)
Low Boost 20, 40, 60, 100, or 140 Hz 0 to 10 dB shelving (1 dB steps)
Mid Cut 200, 300, 400, 500, 600, or 700 Hz 0 to -10 dB (variable Q sharpening)
High Boost 1.5, 3, 4, 5, 8, 10, 12, or 16 kHz 0 to 10 dB (Bandwidth Q: 0.6 to 1.7)
High Cut 1.7, 4, 10, or 28 kHz 0 to -10 dB shelving (Noise/digital filter)
Gain Trim Reference: +4 dBm -5 to +5 dB adjustable in 1 dB steps
Hand-Crafted Excellence: Not mass-produced. True Boutique Independent and US made. Each VT-9M is meticulously engineered, wired, burned-in, and rigorously tested by hand before leaving the workshop. Backed by a Limited 7-Year Warranty (90 days on vacuum tubes).
