[Elecraft] K1 power output on 15 meters

My 15-year-old K1 serial 175 (R.I.P...lightening strike!) with 13.8vdc supply could easily produce 6 watts on 15m, using either a 40/30/20/15m or a 30/15m filter board.

Have you attempted re-alignment of the 15m coils (L3, L4, L7, L8)?  Have you verified the exact number of of specified turns on the 15m toroids (L11, L12)?  It is easy to put an extra turn on toroids (just putting the wire through the center counts as the first turn).  That alone will adversely affect the maximum power output.
