[Jukebox-list] "Clips"-was-Cartridge Installation: ALSO ?

[wbabbott at cox.net]

ALSO, the new cardtridge I'm installing  in the 1438 is a P132D as listed in Ebay Item 110073593922 This cartridge has four prongs. I was told the bottom prongs close together are GROUND and the two upper spaced further apart are input.
Let me know if I got it reversed....
