Do you have an old model Pipeliner or the current model?
The Pipeliner Remote Amp Control has a design change to the machine circuit board that greatly simplifies installation and troubleshooting. No change in the hand control occurred and all are still interchangeable among various machines. This change in design expands the range of machines that can utilize the Pipeliner from 8 to over 57 models. Please find more information on the Pipeliner pages linked below.
Please note the only physical difference between the older model of the Pipeliner and new model is the circuit board that mounts within the machine. Hand controls are interchangeable on both old and new models.
