Albert,
I apologize. I'm not saying that the performance was the same before and after the mods. I'm saying that the mklll with Krebs mods and the Dobbins style direct mount produce similar results. Yes I had issues with rubbing on the chassis and even sent the table and platter back to Bill after the mods. He ran it out of the plinth for two weeks without issue. When I got it back I was more careful putting it back into the plinth to make sure it sat flat and not over tightening anything. I now believe the chassis was torqued or slightly twisted when the rubbing was occurring. It now run very quietly rivaling the direct mount in silence.
To me this is a question of eliminating noted or perceived performance issues with the original table(direct mount) or mitigating these issues with modifications, band-aides if you will. In my experience the band-aides are quite effective. I think it makes sense because both methods address the same issues.
I do agree that ANY rubbing or friction completely eliminates the benefit of the modifications which is why I went to such lengths to figure out the problem. Kudos to Bill for going the extra mile to address that.
I don't want to offend or argue with anyone. I've worked now with all three major plinth makers to good end. No single product has been perfect in every way but all work very well with tweaking. That's the nature of these vintage machines. The headache of getting them maximized is rewarded in the end. It's been a long journey for me but I finally seem to have reached a satisfying end point.
