    Does anyone know of a low power linear, say 2W in/10W out, for use with a CW 20M QRP rig? A kit would be fine if there is one out there, or home-brew details.

    John -

    You are looking for a Mini-Boots style project or kit. There have been earlier offerings / DIY designs for the QRP operator from Doug DeMaw and others.

    NorCal QRP Club featured such a design in their Fall 2000 QRPp journal.

    QST had a low power amplifier for QRP rigs as one of their projects, they had four or five of the designs published, the cheapest one was under $50 the most expensive was a two or three bander with a case for less than $100 IIRC.
