TubeAmpBench

Optimize and streamline your high-fidelity audio builds with TubeAmpBench, the comprehensive engineering assistant designed for audiophiles, technicians, and DIY tube amplifier builders. Move away from scanning obsolete paper datasheets. This professional workbench utility provides graphical load-line visualization, component calculators, and acoustic testing tools to help you design circuits around classic triodes, beam tetrodes, and dual triodes like the 300B, EL34, 6L6GC, KT88, and 12AX7.

Key Features & Mechanics:

Interactive Tube Curves & Load Lines: Browse an extensive Tube Library categorized into Output and Small Signal classes. Select a valve—such as the 12AT7/ECC81, 6SN7, or 2A3—and graphically map its plate characteristics. Use real-time sliders to calibrate your circuit parameters:

Supply Voltage (e.g., 180V)

Load Resistance (e.g., 3500Ω)

Grid Bias (e.g., -3.0V)

Circuit Topology Toggles: Easily switch optimization profiles between Single-Ended (SE Triode, SE Pentode) and push-pull arrangements to match your target hardware configuration.

Output Transformer Calculator: Plan your magnetic core architectures with precision. Compute core dimensions, primary/secondary winding turns, and appropriate wire gauges for any target primary impedance and maximum output power rating.

Acoustic Response Measurement: Capture snapshot frequency data directly via your device's microphone. Map your empirical recording data over the theoretical design curves to quickly expose or debug phase issues in your negative feedback paths and equalization networks.

Dashboard Bench Tips: Reference core hardware protection guidelines directly on your workspace dashboard, such as calculating maximum plate dissipation (plate voltage multiplied by plate current) to ensure your operating points remain securely below rated safe thresholds.

Tailored Workspace Preferences: Adjust the toolset to your workshop setup via the settings panel. Configure custom visual preferences, scale measurement density defaults, toggle session reminders to instantly resume your unfinished bench projects, or manage offline data storage.
