Bill, If you look at the schematic, you should discover that the LPF area will indicate DC continuity to ground. The secondary winding of T4 connects the input of the LPF to ground for DC.
Since the K2 was working before, you have only a single failure point - keeping that in mind while troubleshooting is usually helpful and may prevent you from 'fixing' things that are not broken. I would suggest that you check T3 and T4 carefully (particularly T4), even to the point of rewinding them - while you have T4 out, you could check the LPF for a short to ground if you are suspicious of that. 73, Don W3FPR > -----Original Message----- > > next clue : i pulled the outputs, which are not shorted and the > set acts ok , > that leads me to believe that I got a lowpass filter issue .... > especially since I get almost dead short at the output of the > finals/ input to the LP filters,, > > _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
