    It would be interesting to know especially if the 
compensation was detailed in any schematics or even in parts 
lists. That would be a very good clue for adding it to older 
receivers. I doubt if H would have changed the tuning caps 
but the value of the fixed padders and trimmers might have 
been changed.
