[Elecraft] 10/12M Low Output Question

Does 0.8W output on 10m/12m sound more like a problem with the lowpass 
filters or with T2 being too close to the board?

I re-peaked the 10M inductors at 28.2 and again at 28.4 just for a test, 
and still get just under 1W, either directly into a good dummy load with 
the KAT2 measuring, or with an external wattmeter.  I haven't tried 
twirling the 12m trimmers.

I bought T2 from Mychael so I know it is optimally wound, but I mounted 
it tight to the board, which I know is wrong, but it seems that this 
gives 5-6W out instead of the <1W I am getting.

I am looking for advice on whether my next step should be to remount T2 
(which will require rewinding it as the leads are clipped now), or 
taking a deeper look at the filters.

Might an RX sensitivity test tell me something here, as I have the XG1?
