The design is now 95% stable, I already have linear output of 10W, good for SSB or the digital modes. Driving the amplifier into saturation, output for CW is between 15 and 20W. It will probably take me one more week to populate and test the final PCB layout, but for anyone interested, you can see the design on this web-blog:
