Calculators / Info

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.

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.

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 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.

Selguide is a software tool designed to guide the user in selecting our Operational Amplifier, Buffer and Comparator products by enabling the user to enter in a few key parameters and have a list of devices meeting those parameters returned to them. Included in the results is a summary table of key device parameters and pricing information, as well as a link back to view our Web site product folders for the chosen devices (You must have a Web browser and a live Internet connection to view the web pages). Installation of the Selguide software is simple and painless. Selguide does not add to or modify your system files at all and is completely self contained within one folder. Selguide fits nicely in a corner of your Desktop or Laptop PC for easy future reference.
