Hmm... you may have shorted turns in the modulation transformer, but it is
difficult to know without terminating the secondary with a resistive load,
and measuring the power output.  I would assume the transformer is the
correct part and hasn't been subsituted somewhere along the way.

I just confirmed that the grids of the 833s are indeed being fed 180 degrees
from each other.  One signal had more RF from the driver (only low B+ was
than the other, but otherwise all seemed normal.
