[R-390] IF Subchassis Resistor Value R-390

The following was stated in Hollow State News #36, page 5 [Metz]:

"R554 coming off Z503 is schematically 2.2K.  In four IF decks, the
installed value was 470 ohms (and looked original).  I temporarily removed
this resistor and used a substitution box to experiment.  It seemed that the
470 sounded much better than the 2.2K or any other value for that matter."
