[DW Holtman]

Hello,   I have a 2B receiver that was working great It has been re-capped and the controls etc cleaned. This afternoon it quit working on 20 meters, later it quit quiking on 40 meters. 80 still works great. I swapped out 20 and 40 meter crystals, tested the 6U8 osc tube, no help.   It seems that the higher frequencys will not oscillate. I know that a tube tester checks at 60 hz (at least mine it is a emission tester) so could it still be the tube?   Any help from the group would be great.   73's DW Holtman WB7SSN
