The Lamington valve amp design was uploaded as a free resource in 2008 and has proved to be very successful with hundreds built here in Australia and overseas. Builders regularly comment about how great this amp sounds, with chimey cleans and strong overdrive tone. This design will continue to be freely available here for more experienced constructors. It is ideal for the builder who has some experience building electronic projects, has the capacity to confidently layout and fault find the amp and has the time to gather and source the parts.
This valve guitar amplifier is designed for the person who has experience with electronic construction and a healthy respect for high voltages who wants to build a basic 15W valve amp head for minimal cost and with a minimum of metalworking. It was designed and constructed to prove that you can build your own 15W amp using readily available “off the shelf” components here in Australia.
Depending on how adept you are at scrounging certain components to save costs, the cost to build this amp will be around A$250. It was designed to be built without access to a workshop or specialised tools.
For less experienced builders, Valve Heaven has made available a comprehensive Construction Manual. This step by step manual assists the newcomer to amp building and comes with email support from Valve Heaven for assistance with any questions that may arise during the build.
In addition, for those who don’t have the time to chase around for the parts for this amp, Valve Heaven provides a comprehensive Amp Kit containing all parts required for building the amp. This is often a cheaper option than purchasing all of the parts from retail suppliers. The kit also saves you the effort of punching and drilling a chassis! This kit also includes the Lamington Construction Manual with email backup for the constructor.

For constructors who continue to have problems with their build, Valve Heaven provides a repair/debugging service for $50 plus post – contact me for more information.
And last, but not least Valve Heaven holds Amp Schools throughout Australia for newcomers to valve amp construction. Over a weekend, the student learns valve amp theory and is personally guided to build their own Lamington 15W valve guitar amplifier.
