When building a piece of audio equipment by yourself you have several advantages over buying a commercial user-ready product in a shop. (read more by downloading pdf at left)

D-123 Manual
1. Introduction
After former experiences with class-D amplifiers, we at Hawk Audio wanted to create something small at an
even more reasonable price. Another consideration was we want to live in a “greener” world; less amplifier
power also means less energy consumption.
Over the past years, a range of integrated circuits (ICs) were developed including the generation of a switching
signal and the possibility to drive power transistors. Most of these circuits need extra circuitry for safety
purposes (current, tension and temperature control). Those circuits are less convenient for the active DIY audio
amateur. A new solution was introduced by Texas Instruments (TI); after creating some designs for mobile
purposes, they developed a chip including all types of protection and the power transistors. Originally that chip
was intended for use in the television industry, to be included in flat screen televisions.

LD+/Signature Mk2 91 Manual
The LadyDay+ is beautifully simple and designed to really display the advantage of a directly heated triode 300B in single-ended class A, no global negative feedback configuration. Using a tube rectifier and choke filtered power supply it gives true musicality - especially when connected to horn and single driver full
range speakers. The self bias design and optional hum pot (included) enables 300B tube rolling to be an easy task for everyone. The Basie/ Tram and Django linestage kits all work well with the LD+ and are highly recommended as a sonic and aesthetic compliment to the LD+.
