[C320-list] Adler/Barbour refrigerator

[--Bill]

When I purchased #240 it only had the evaporator section of the Adler Barbour system, no compressor section.  So currently I have 12V wires and plugged male and female tubing connections in the port locker. The tubing is still connected to the evaporator in the refrigerator/ice box. 
To restore the system do I just need to connect a new compressor or do I need to start with a new evaporator/tubing in addition to a new compressor?  Is this a DIY job?
