Hey there, So I have a Sony APR-2003 that the little plastic part that allows the record knob to stay locked in record mode cracked in half and fell out of the bottom of my deck. I have read around the web that this and the sister models the TC-510-2 and 5550-2 all have the same part failure. Some folks had mentioned that there was someone machining or manufacturing a replacement? Just seeing if anyone might have a leads towards whomever might have be doing this or any other suggestions, before I just end up trying to epoxy the piece back together. Thanks for the help folks.
