Arriving late to this party, but hopefully the answer to my questions will help others of us less sophisticated circuit tweekers. Thanks as always for your shared expertise.

1. Can the SA5.0A "primary" TVS alternate be installed across the external terminals of the TIU channel? If so, the output side (or input)?

2. Can the added "beefy clamp" be the two 1n4148 diodes, in parallel but opposite polarities, likewise be across external channel terminals, output (or input) ?

3. Finally, do these steps all apply to any Rev L TIU, or only certain ones after a certain production date?
