Adrian,
I commend you for your effort of diagnosing this problem and providing us with a solution.
John,
Just wondering if you had any success with the prototype you designed for the TIU? Ive noticed there has not been a post in this thread in over a month, and just wondering if there are any more updates with your prototype.

Well at AGHR we haven't had a single weakened TIU channel in the 9 months since the changes at the top of this post. We used to break them weekly.... Every Saturday I go around with the scope and re-validate all 20 channels (4x5TIUs) one by one, and I haven't seen any changes in signal excursion since we started. I think the design adjustment is solid, so the only thing left is to figure out how to easiest apply it for those that would like to. That's more GRJ's dept, I'm just a circuit designer.
