On a brief visit to Chicago recently, I discussed the appropriate method for adjusting the VTF on a Regs RB 300 with Bess Nivera of Music Direct( he is extremely knowledgeable apart from being a wonderful person). This was in the context of using an Expressimo counterweight. If I understood correctly, you need to dial in the max VTF(2gm) using the small counter on the RB 300 base and then adjust the VTF by moving the counter weight to achieve the desired VTF with a stylus guage. This is somewhat contrary to what I imagined, namely set the VTF counter to zero, level the tonearm paralell to the platter and thaen dial in the desired VTF using the tonearm VTF adjustment.Am still not sure which is the optimal path. The approach suggested by Bess seems to suggest using the Rega's spring adjustment to best advantage.Tonight, am going to readjust the VTF on my RB 300 Lyra Helikon combo using the Expressimo counterweight and will be happy to share my experiences.
Cheers
