Norton posted:Junior, at least two of us, John and myself, have rev Ls that never came with the tiny TVS's. Both of ours continue to work. I have put a scope on mine and it shows full output of 6-8v P-P on all channels. If yours stops working then send it to an MTH tech and have it repaired. For any electronics guy worth his/her salt this is a simple repair.
John, I would suggest doing at least one TIU, yours or your clubs with one channel using MTH's suggested component for a comparison. If theirs fails and yours doesn't then maybe MTH will adopt your fix.

8V pk-pk is about where the trouble starts. 14V is perfect 12V is okay, 10V is where things get noticeably slow with adding engines
