A friend asked to me to repair his K2 10W which has a strange problem: too high current in TX (1.2A even with 0.5W) and current that increases during key-down until HiCurr protection. Already changed the 2 x 2SC1969 PA transistors and re-winded the output transformer, but nothing changed: the voltages on PA and driver seem OK, the power from driver and the power output remain stable during key-down, but the current increases... What could be the issue? Before spending more time on troubleshooting, has someone had and solved the same problem? Thanks and 73 Guido, ik2bcp ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
