Amplifier Kits Directory Listings

Allen Amplification - Most of Allen Amplifier's manufactured models are available in kit form at substantial savings due to the extensive amount of time involved in point-to-point hand wiring. The cabinets come completely finished with faceplates and logo. Most kits have step by step instructions to guide the assembly and wiring. Building the kits requires that you enjoy this type of work, know how to solder well, pay attention to instructions and details, and typically finish large projects that you start. These are advanced kits, so you should have some basic kit building skills, and most important, soldering skills! Typical kits can take from 15 to 25 hours to complete. If you follow the instructions, you are never exposed to live circuits or dangerous voltages. All parts are guaranteed except shorted transformer windings, torn speaker cones, or similar abuses incurred after you receive the kit. Speakers and tubes are guaranteed for 30 days.
