GTC Mark V PTBA
The OEM says your equipment is “obsolete” – GTC calls it “Classic”, with the ability to operate safely and reliably for as long as you need. We developed a direct replacement that consists of the same fit, form and function as the original, but with the added benefit of upgraded components. We offer clients both options to buy the original OEM or the GTC direct replacement. Ask your GTC Sales Representative for specific details and data.
GTC offers its HMI Replacement In Kind (RIK) product for Mark V, Mark VI & Mark Vie to operators looking to replace their ageing CPU hardware with new.

Parts are made up of Unused and Remanufactured condition all of which are supplied by GTC’s 3 standard year warranty which is also extendable entering the GTC Extend Warranty Program.
GTC continuously buys surplus and disused GE Turbine and Excitation controls, as well as faulty cards. We invest in excess of over 2 million USD annually to keep inventory available to Operators who can no longer buy from the OEM or choose not to buy from them. With the many hours we put into each and every part we purchase to remanufacture and test, buyers are always guaranteed to receive the highest quality parts which are considered to function as good as, or in some cases, better than new, as improved components are used where possible.
Next time you upgrade your system, part of your system, or have faulty cards you wish to dispose of, connect with a GTC Representative and we will give our evaluation.
We offer a full range of services onsite or offsite for the GE Mark II, Mark IV, Mark V, Mark VI, Mark VIe, MarkVIeS, EX2000, EX2100, and LS2100. To learn more, click here.
