Pioneer Spec 1   Mic Mixing Assembly (Push Pull Switch.) & Full Wire   ACV-507-0

(((Great Condition Clean Fully Operational! No Damage!   READ!!!.)))----

This switch is an early production switch for the Spec 1 It is a ACV-507-0 (NOT a ACV-507-A!)  The difference is the stem.  the switch we have here (ACV-507-0) has a forked spindle type stem which takes a different knob with no Set Screw (AAB-098).  When you pull the knob to adjust it would come off in your hand.  Thats why Pioneer upgraded this switch to the ACV-507-A which then needed the knob with the set screw!  Your knob may work with this switch just do not overtight the set screw!!  Or order the correct knob (AAB-098) and when installing put a drop of Goop inside that will glue the knob in place with no further issues but you will still be able to remove the knob for maintenance!
