Tone Stack calculator

The Tone Stack calculator is designed to help you check out the design and response curves of a variety of tone stacks used in popular guitar amplifiers. It is intended to be of interest to amplifier technicians, amp modifiers, hobbyists and students.

Tube DataSheet Locator

The TDSL (Tube Data Sheet Locator) Personal Edition provides information right on your PC for a large number of vacuum tubes. Advanced searching facilities help you to compare different types and make substitutes for hard to find vacuum tubes. It is intended to be of interest to amplifier technicians, amp modifiers, hobbyists and students.

Speaker impedance calculator

Tired of working out what the individual power ratings etc.? Grab an Excel 5 spreadsheet that will do it for you!! Handles various combinations of series and parallel to give you the power rating required for each speaker, and the impedance of the whole combination.

Ohm's Law calculator

A simple little Ohm's Law calculator - input two of the known values (power, voltage, current, resistance) and get the last two calculated. Might be handy for quick calculations - has been for me, anyway.

Wire Gauge Calculator

Wire Gauge Calculator converts between trace geometry (width and thickness) and equivalent AWG wire gauge. It also calculates trace resistance at a given length and temperature, and voltage drop across the trace for a given current. It is an update to the previous version, written in VB.net and offers better OS compatibility.
