Let me clarify: The tuning knob that my 620 currently has installed is the knob furthest away from the chassis. I believe this knob is used for general braod tuning. The knob that appears to be missing is the "inner" knob closest to the chassis that probably is used for fine tuning. If anyone knows where I can obtain the "inner" knob (or both) for that matter, please let me know. Thanks again!
