 "description": "Amp Tech Toolkit puts the calculations and data a guitar amp technician reaches for in one place, with records for every amp on your bench.\n\nTUBES\n• Datasheet ratings and bottom-view pinouts for 37 preamp, power and rectifier tubes\n• Tube swap checker: direct swap, rebias, only if the amp is designed for it, or not compatible, with the reasons\n\nBIAS & POWER\n• Bias calculator: target idle current for any dissipation percentage, and checks of measured readings per tube\n• Cathode bias: current, dissipation, resistor and bypass capacitor\n• Power supply: B+ estimate, ripple, filter stages and filter-cap discharge time\n\nCIRCUITS\n• Tone stack frequency response with knob settings and editable part values\n• RC filters: coupling, plate-to-grid, bright cap, cathode bypass, interstage dividers\n• Ohm's law, resistor power, series and parallel, voltage dividers\n• Resistor colour bands, capacitor codes and standard values\n\nSPEAKERS & SIGNAL\n• Speaker load: cabinet impedance, how power splits between speakers, and output tap matching\n• Output transformer ratios and reflected loads\n• Decibels, volts and watts, and output power across a dummy load\n• Tone generator: sine, square, triangle, sawtooth, noise, sweeps and bursts\n\nRECORDS\n• Amps with tube complement, output taps, fuses, a bias log with per-tube readings, service log and photos, and a one-page service sheet\n\nEvery tool explains itself: a short guide the first time you open it, and ⓘ notes on the fields. Works offline. No account, no ads, no tracking.\n\nTube amplifiers contain lethal voltages. This app is a reference for trained technicians; check every value against the schematic and data sheets.",
