Hello all. Yep there were multiple hairline cracks, all fixed now with all control restored.

I do however need to replace the (Sharp)IR94558 op amp in the mixer section (IC1) as it's crackling. I can get a new Sharp IC but it's rather expensive. I'm inclined to stick with sharp but would anyone perhaps suggest using the cheaper JRC or the like?

Thx
