[JRC] Unblocking the NRD-545

[Brooke Clarke]

HI Chris:
 
Is there a typo in the first line?  "While scanning through the service 
manual, I noticed two resistors, R24 and R24 on the mainboard."
                                                                         
                                                                        
     ^^^        ^^^
