Deluxe 112 Plus crosstalk / switching issues

[Mr_bibbles]

WOoOf, I was looking at u6, don't know what I was thinking.

I'll test the AC points with the 1k signal as suggested, but my guess is that I need to increase the gain to the IC stage u3, would my assumption that increasing the value of r25 be viable?

SO I'll admit I don't really know what I'm doing here but I found the issue, it was in U3A not U3B. Reduced the value of r28 (470k) and the problem disappeared. I know enough to understand I have to properly bias these IC's as you would with a tube stage, but I don't fully grasp how I eliminated the crossover distortion.
