Well, I'll start with a check of the ALDA. Our mechanic had at first told us we'd be best off with another IP - then a year later came up with the "hole in the ALDA diaphragm" thing, leaving me rather confused. It's our daily driver, and it's time to fix whatever the problem is.

Brandon had mentioned, after checking our Ava out, that he had finally given up tinkering with his, and purchased a used, bench re-adjusted and re-sealed IP - loves the results. I'm at a total loss of where to even start searching for such a thing - also want to rule out a bad diaphragm first.
