We are planning to replace our exhaust thermocouples on a frame 6B unit and are evaulating the following vendors.. Powmat, Ametek, and Conex. What are your experiences with each vendor and which do you use? any other vendor suggestions? thanks

on our 7Fas they were shipped with Ameteks but the OEM is now offering Conex. They might have been the low bidder that got approved on the vendors list. Ive heard of TC issues a few years back with Ametek that were notoriously failing with less than one year of use. Powmat is a great alternative source but I have no experience with them.
