Kent 5999 preset

verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Kent 5999 is a small budget tube amp with tremolo, sold under the Kent brand. It runs without a power transformer: a series-string heater chain and a single diode rectify straight from the mains. A 12AU6 pentode preamp drives a single-ended 50C5 output tube with volume and tone controls. A 12AV6 tremolo oscillator has a strength control and a footswitch jack.

• Channels: 1
• Preamp tubes: 1× 12AU6, 1× 12AV6

Schematic-derived preset files for the Neural DSP Quad Cortex and 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
