    Thank you this is really helpful. How good is the bandspread 
calibration? Mine is very far off. I've centered the capacitor 
plates and tried all sorts of other things. I can't figure it 
out. I have been told the dials are pretty accurate (considering 
the age). The error is progressive.
    I have a set of plastic film caps to replace the original 
paper ones, perhaps that will make a difference. The original 
caps are green molded body with paper labels. The ones I tested 
were not too bad. However, because of the mechanical mis fit and 
some other things I wonder at the provenance of this thing. I 
wonder if the dials from the later receivers would work in the 
HQ-120-X. If they are the same I can get that to work and see how 
the two compare. While there were a number of changes between 
them they are essentially the same design.
