After a few months of the RF POWER levels falling lower and lower, I now have no RF OUT on 10 thru 17 meters and 20 meters only has 5 watts out. Yes this is with the KPA100 attached. The remaining bands 30 meter thru 80 Meters have about 25-30 watts RF out and 160 has about 12-15 watts out. I have changed the pre-driver ,drivers and the finals in the base K2 -NO-Change ,then I changed the bias transistor to the Finals -NO CHANGE.. Anyone have any ideas of what is happening to now have lost RF out on 10 thru 17 meters?????? Serial #4670
