If anyone has one of these being cannibalized for parts, I'm fixing up a couple of HS-J09's. Mainly I need a volume control. The reference is # VR-1, and part # 87-021-985 20ka S. The other models listed above use the same part number. Not as important, I need a gear idler for the radio dial tuner assembly part # 84-417-213. This is the tiny white plastic gear WITHOUT the spiral thread shaft that goes to the tuner itself. And if available I could use one white switch button, both black radio control buttons and miscellaneous screws. I'm not even going to ask about a spare battery compartment lid. I've made my own buttons and battery lid, but original ones would look nicer. Thanks in advance!
