Correct. Not the center leg
Yes I get rail to rail oscillation but its not at the correct frequency
No. The amp does not go into protect

Only clocked amps always oscillate at the same frequency. Self-oscillating amps like these can vary in frequency and will during normal operation.
You need to find what happened between post 110 and now. Why won't the working half of the amp work like it did previously.
Could you have possibly mixed the inductor from the previously working half with the one that had a problem?

Are you saying that the replacements are different compared to the original?
What happens if you try the original that was working perfectly?

I dont think thats the issue. I have 2 of these amps and both of them have the same issue. It appears to be a common fault with them. All I get on the speaker terminals is a triangle-ish wave. Now all of a sudden I have .7vdc on the speaker terminals. I swear things change on this amp seemingly out of nowhere.
Here's where I'm at. With one leg of each inductor pulled i installed fets on one side and powered it up. On the side with fets in I get normal operation but on the other side I see a triangle wave on the the drain of the low side.
