[Elecraft] [K2] Transmitter alignment, No output on 12m

[KC8YFH]

Hi all,

I am working through the last stage in transmitter alignment - page 80 - and I've come across a problem.  All goes smoothly until I switch to 10m.  There I can maximize power output, but only to 1.9 W or so, so just shy of the 2 W target by adjusting L12 and L13.  When I switch to 12,  there is no output registered once I switch over to "Tune".  Adjusting C44 and C46 has no noticeable effect.

I've made a careful inspection of the circuit board, and I don't see anything obvious.  I was wondering if someone here could help me localize the problem?  

I was able to listen to some CW on 12m, but it wasn't a very strong signal.  I'm listening on a buddistick inside my house, so I don't think I can expect much.

Thanks for any guidance,  
Joe
