RedRoo Amp - New chassis and Kitset

Hi all. Just letting you know that I've redesigned the RedRoo 5W SE amp to use a powder-coated steel chassis.

I'm also now offering it as a kitset (less the valves and external 12V transformer which many people will already have lying around).

If you want to roll-your-own chassis or use a timber case there is a version with a precision-drilled top plate only.

Or you can download the full design for free from the website, and maybe just purchase the pc board.
