I had a damaged backplane of a Mark VI control chassis during peak season that took my unit out of services. This assembly was not in GE stock and had a long lead time and hefty price tag. Roger McLean of GTC hooked me up! He diligently used his resources and located a chassis for us, sent us pics to ensure it was like a replacement, inspected it and shipped it directly to us the next day. The part was brand new and exactly as it was described with a fair price to boot. GTC is the sole reason IU was able to minimize my downtime due to a controls failure.
