I was wondering if anybody knows if you can get decent After market control knobs for a Cobra 29 NW ST radio. I've been using mine lately on a temporary basis and I've always hated that stupid ( in my eyes ) rectangular on and off control knob with it's sharp corners. I'd like to replace it with a round knob if I could because I love the radio except for that little rectangular knob. Thanks in advance for helping this Old Fussy Dude. LOL
