I have just finished prototyping a new 2W Valve Heaven amp design called the “Lamington Junior”. I’m pretty pleased with it, as the design has been a long time in development. The design brief was for a low power amp that delivered a significant amount of clean, “chimey” headroom and also a great overdrive tone which is what it delivers! What is especially cool is that it runs from a 12V AC plugpack, so a newcomer to amp building can do so with no contact at all with the 240V mains making it a safer amp to build.
I am currently building a second prototype which will be easier to construct. I’ll soon have the design details including schematics available here at valveheaven.com. Soon to come will be construction manuals and kits for prospective builders.
Watch this space 😉

Well, as promised, I have now posted the full design details and schematic diagram for the Lamington Junior here. I am very pleased with this amp, and it has now become a favourite here to play through at home, and I feel sure it will become as successful as its big brother, the Lamington 🙂
I will be making full kits and a construction manual for this amplifier available early Feb 2015 for $195 plus post for the DIY kit and $49 plus post for the DIY manual. Kits and the construction manual are now available.

Several Lamington Junior kits have now been purchased with the builders very happy with their new amp. I just received this email from a customer who had never constructed an electronic project before:
Hi Grant,  I finally got it working (1k8 was in the wrong spot), all good. Thanks for your help, I will play with this one for a while and then i will try the Lamington 15w. Since I have no previous electronic experience I found the whole kit very easy to follow as a beginner. Thanks again!
