Good point. I know in my SB-1000 the transformer is the limiting
factor in continuous carrier (RTTY) operation, not the tube. Could be
the same for Ten-Tec. 

My rule of thumb (finger) is if the transformer is too hot to touch,
it's too hot to run. Transformers are made of materials that are much
less heat-tolerant than tubes or resistors, for example.
