DC JACK Power jack fits the below consoles.
These aging consoles really benefit from a brand new dc power jack. 
Old power jacks are often rusty, cracked, and the leaf is weak causing poor contact. 
Its highly recommended to replace that old worn DC jack with a brand new unit for the most reliable power connection. 
 
Soldering required. 
This DC Jack is intended for the following consoles.
