Solton BV150 - Normal preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Solton BV150 is a Hiwatt DR103-style 150-watt head. Brilliant and Normal inputs each have their own ECC83 stage and volume, mixed into a further ECC83 stage and a DR103-type treble/middle/bass stack. This drawing also shows a master volume and a MOSFET source follower ahead of an ECC81 long-tail phase inverter with presence, which drives four output pentodes, each with its own bias trim, from an 800 V silicon-bridge supply with standby and 4/8/16-ohm outputs.

• Wattage: 150W
• Channels: 2
• Preamp tubes: 2× ECC83, 1× ECC81

Tags: high-wattage, clean, two-channel.

Schematic-derived preset files for 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.
