Fired up the new SkyWave 2879ABTC with the temperature compensated bias
tonight. It worked like a million bucks. I adjusted (using the
available final-tweak resistor pads. You might see it sticking up in
the air in the picture) the AB bias current for 500mA at room
temperature. I transmitted and ran the sink up to 80 degrees C and the
bias was 530mA. I ran out of time and was unable to test it cold... but
I believe the circuit will work as the first proto. Here's a picture of
the amp on the bench in testing.

interesting to hear

anything on it preforomance on 10 or 12 meter Ham band?

Not as of yet... just got fired last night. Expect the performance to
be equal or better than the existing SkyWave 2879AB amp. The specs are
available at http://www.telstar-electronics.com/SkyWave%202879AB.pdf
I have much more testing to do before this product is released sometime
in late October.
