The satisfaction of doing it yourself as well as the often substantial savings available can be very satisfying. We see TV shows encouraging people to take on home renovations, an undertaking that is far more complex than building a tube amp. And now there is Amp Camp, a supervised workshop that guarantees your success!\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eAmp Camp caters for all hobbyists, from those who may never have lifted a soldering iron all the way to trained radio engineers and electricians. Amp Camp offers the tools and space, the highest quality kits plus skilled guidance and a comfortable environment in which to build.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAmp Camp is an enjoyable build experience, providing instruction in mastering the skills and using the tools as you build your own tube amp. It is about the practical rather than the theoretical. The objective is to successfully build your own tube amp. Your first camp day therefore starts with a short course in Soldering for mastering the techniques and avoiding the pitfalls, which if not understood, may compromise the project’s outcome. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\n\u003ca name=\"_Toc141965439\"\u003e\u003c\/a\u003eOnsite Facilities\u003c\/h2\u003e\n\u003cp\u003eAmp Camp offers a dedicated, air conditioned, purpose-built workshop facility complete with coffee and music as well as a sumptuous lunch, sourced from one of our favourite local eateries.

Moving coil cartridges exhibit very low output voltages, usually around 10% of a MM cartridge. Without a step up transformer the resulting signal does not present a satisfactory input for the phono preamp stage.
LL9226 is an MC transformer based on (and pin compatible with) Lundhal's classic LL9206, but with reduced copper resistance and level capability. The new design has resulted in an even better frequency response but still with enough no load impedance to maintain the LF bandwidth. The transformer is built up from two coils, each coil with one secondary winding surrounded by two primary windings. Advantages with this structure are excellent frequency response and high immunity to surrounding magnetic fields. All winding ends are available on the pins. Thus, the transformer can be used with a set of different turns ratios.
The Red Roo phono preamplifier is designed with interfaces to easily accept the LL9226 for moving coil cartridge support. Installation of two LL9226 transformers converts one of the two MM interfaces to MC.
