Back in January we had Giveaway #1 and gave away a copy Building Valve Amplifiers by Morgan Jones to Bill in Georgia. Well, with Spring just around the corner we are in a good mood and are having another giveaway. Once again the giveaway will be held on the DIY Audio Projects Forum and you will need to be registered on the forum in order to enter for the giveaway.
The giveaway is for two mono kits (which will make one stereo pair) of the MyRefC LM3886 chipamp. The kits were recently put together by Uriah and Peter as part of a large groupbuy. The groupbuy was a very large effort so thank you very much guys (I got a kit for myself that I will build shortly). Also included in the giveaway are two 160VA (120V primary, dual 24V secondaries) transformers for use with the amplifier modules. This will allow you to build two mono-block amplifiers if you like. To finish off the amplifier kits, you will need to supply your own audio and power hookups (RCA, Speakers, IEC, power switch, wire ...) as well as a suitable heat sink and chassis (or two). A photo of the kit contents is shown below.
The chipamp design is by Mauro Penasa and it has been well received. A schematic of the amplifier is shown below.
In order to enter for the giveaway, you need to post a message in the Giveaway #2 - MyRefC LM3886 Chipamp Kit thread with one or more photos attached and a brief description of the photos. Complete details and giveaway rules are provided in the message thread. The giveaway ends April 10, 2009 at 18:00 (CST) (UTC-6) and the winner will be chosen at random.
