Correction / Improovement for my Scanner Vibrato / Interpolating Scanner

I noticed there is a tiny, but not unimportant design flaw - I'm surprised no one else mentioned it so far: The output amplifier gain is too high. That means, the output will clip hard and nasty way before the scanning transistors go into soft limiting action. Ok, there is a lot of ugly/hard clipping gear out there, so probably that's the reason nobody complained, but that's not the way I normally design my audio circuits. My apologies. - Fortunately, this can easily be fixed, by just changing two resistors. What has formerly been 13k, should now be 4k3. I won't redraw the schematics diagram, but here is a correction of the PCB layout (applies to all versions):
