Damaged Barrier Strip

The ground screw of the input/output barrier strip on a 310 that I’m refurbishing had a seized thread that caused someone to twist the head off. After a little research, I found that the Cinch 5-140-Y barrier strip is an exact replacement. If you need to order one, be aware that many of the pictures that sellers use for these parts are incorrect. The “Y” terminal is a solder tail that feeds through back panel into the case.

The original on this one was made by Kulka, but the Cinch fits perfectly. Cinch may have been used by the factory in some models.

Remove the existing strip by removing four screws. Let the strip hang away from the back of the DAP. Gently remove the heat shrink tubing around each wire. Thread each wire into a short piece of 1/8″ heat shrink tubing before sweating it back onto the proper Y solder tab. Shrink the tubing so that none of the wiring can short against the metal case. Re-install the strip. Good as new.
