I haven't started building a new plinth for my TD125 yet, so there's still a possibility of building an LB version. Did you make a new plinth as well? If so, are you willing to share info on (inner) dimensions and construction? And how did you solve the resonance problem of the wider armboard?
I just got things up and running yesterday evening, so I haven´t listened very much, but i can tell you that there is a significant improvement over my td150 with Audio Technicha 1100 tonearm. I bought my 125 lb without a tonearm, so I can´t compare the Jelco to another arm on the same deck. I strongly recommend the arm, it is a joy to handle!
I got the original plinth, with no other modification than a 1" thick solid wood bottom plate instead of the original flimsy thing. I will refurbish or maybe build a new plinth in due time, we´ll see what I´ll do. I got no drawings though, sorry. I would also love to have them.
I haven´t taken care of the resonance issue yet, but my plan is to add adhesive damping material along the underside edges of the armboard, ca 15 mm wide strips to save weight.
This is not the right place to discuss my project however, this is for springs vs. rubber. If there is more to say about my discspinner I suggest we´ll do it here:
