Unable to fix TJ2A Update june 24 2013



I've found that the problem was a Fake!!  C2078 transistor that I've bought on internet.
Today I received  new ones bought from Eleflow and now I have, in cw, 2 watts on 20  meters and 4watts on 40 meters.

Unfortunately I have a lot of un-sopressed carrier on LSB, about 1 watt!!.
I've tried lovering r62 but the carrier is still there.

I must re-study alle the schematics to find the problem.
Someone have suggestions?
