Amp Tech Toolkit
Calculators, tube data and service records for guitar amplifier technicians.
Safety
Tube amplifiers contain lethal voltages, even when switched off and unplugged. Only work inside an amplifier if you are trained to do so. Figures in the app are references; check them against the amplifier's schematic, data sheets and your own measurements.
