[Jukebox-list] "Clips"-was-Cartridge Installation on Rockola 1438 ?

[Ron Rich]

Clips (or socket pins) should be included with the new cartridge-- Contact whomever you got it from--Ron Rich

If no one has a better suggestion, you might look inside a discarded PC 
(computer) (as I did recently)

There, you will find gold plated "clips". They are located inside the 
plastic plugs of the power wiring harnesses. There are different sizes of 
these "clips" to be found. Some might be just the right size.....
If you cut away the plastic you could tease out a few of these "clips" and 
see if they are the right size to make a good friction fit onto the cart 
pins.

If so, just cut them off their wires and carefully solder them on to your 
cart wires. Maybe a little heat shrink needed too.

For What Its Worth,
Don
