Just a quick follow-up on my last post. Contacted Digitrax about possible repairs to the DS-64s and they said to send them back to see if they could be repaired. As the repair cost is only $20.00 each, I figured it was worth a try.....

  Well Digitrax couldn't repair them, but since they were still under warranty (I sent a copy of the receipt with them), Digitrax replaced all 3 units..... for FREE!

  Kudos to Digitrax for excellent customer service. The units should be back in operation this weekend - with the correct connections for AC power this time!
