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.

This is a small program to find transistor data. Not everything is listed (1442 different devices). Download a copy, place it into the directory of choice and run the program, which is a self extracting archive. There are two extracted files - ESP-TRAN.EXE and BIPOLAR.TXT, being the executable and database respectively. ESP-SEMI.EXE may be deleted after extraction unless you want to give a copy to someone else. New stuff can be added as you find the data. If you add a lot of stuff, feel free to e-mail me a copy of the new database (compressed, please!), and I will add it to the database file. For users who eschew Windows, the text file is still useful, as it can be read with any text editor or even a spreadsheet (TAB delimited format). Be careful with spreadsheets, as they like to try to convert some data into dates (really useful - not!).

There are two ways to connect a pair of speakers together. You can have series or parallel. Easy enough? What happens when you hang that twin speaker extension cab off your 1 x 12"?? Hmm... gets a bit more complicated. I've put together an Excel 5 spreadsheet which caters for many different wiring combinations of 2, 3, and 4 speakers. Given the power output of the amp, it will work out the total impedance that the amp "sees", and will work out the individual power within each speaker. It has pictures of the different configurations within the spreadsheet, so you can use these as a reference for wiring the speakers up too....
