Not enough power to run my Robotic Arm AL5D

My school purchased 10 PLTW Robotic Arm kits this past fall. We are just now beginning our unit on robotics, however, my robots will not work. The robotic arm does not have enough power to run all 6 servos at the same time. It will run all of them except the shoulder servo, 805BB. When I unplug that servo, the SSC-32U has enough power to run all the other servos. I saw a post in the forum about the power cord. I have a 6V 3Amp cord. I feel like I need more power? Any suggestions?

This is a known issue. Please send an e-mail to [email protected] with your order number and indicate the number of 6V ,3A power supplies you have. We will replace them with 6V, 5A power supplies. We apologize for any inconvenience.
