I have a gl75 in stock plinth with rega 300 arm. Apart from the arm change i have removed bottom plate and springs, done the spring tweak, and added plasticine for damping around the main bearing, between top plate and plinth contact areas, idler arm, under platter around spindle area. I also added an extra platter damped with plasticine from a cheap throw away dd tt. Sounds great. My sister just got a gl75 completely stock and it sounds great too. In fact she is getting rid of a lp12 and keeping the lenco. I have not compared my lenco to hers yet but I would be surprised if the cheap and simple tweaks don't produce a better tt. Enjoy your lenco they are great.
