Test Equipment and Software

ModelSim Designer ModelSim PE	ModelSim A comprehensive simulation and debug environment for complex ASIC and FPGA designs. HDL languages include Verilog, VHDL and SystemC. For when one just has to develop that "perfect" DAC filter or a "proper" digital audio data controller. UK Representative: Saros Technology

	"Tube CAD Journal Push-Pull Calculator helps tube audio amplifier designers develop push-pull output stages that yield low distortion and long tube life." A useful and very affordable program for developing Push-Pull driver/output stages. Tube types available includes my much loved 6C33C as well as more "conventional" parts like 300B, etc. Definable load allows for 600 ohm line driver development as well as speaker type impedances.

	FFT Analysis with WINaudioMLS software The software, in conjunction with an E-MU® 1212M soundcard, that produces the million point FFT graphs that grace this website. PRO EX Version + 64-bit ultra high precision FFT; 192kHz/24 Bit ASIO support.

General Interest

	Best website for ongoing Tube development, information, understandable theory and how to put it into practise. Home of the Aikido preamplifier.

	Interesting tube and speaker projects, including a straightforward TX-102 based TVC.

	Per-Anders Sjöström QRV-07 - "The ultra high performance SMD headphone amplifier" based on the TI TPA6120. Makes a good line driver for Zeus power amplifiers.
