I'm in the process of modifying a Kenwood TS-520s (IF Output) for receive single observation for use with the SM-220. However I can't locate a few small parts I need. Maybe someone out there just might have them lying around in their parts bin. . They are as folllows... A. 1 - 22 Pf 25V capacitor B. 12 to 15 inches of 75 ohm miniature rf cable. Thanks... 73 Ray N6XVO
