Re: Kenwood TKB-620, TKB-720 or TKB-820 versus TKR-720 or TKR-820 However, you can use the parts from one to repair some of the failures in the other(s). There are quite a few differences in the sub systems and on the display - control main board but the same repair parts do interchange. Same with using a mobile radio for parts... as in the example of the RF Power Amplifier Module.
