I am having a turntable assembled to accommodate the Ortofon AS309S tonearm. I intend, by way of two arm boards, to use both the traditional SPU-G headshell and the SPU-A headshell. My question: In reviewing photographs of the most recent SPU-G and SPU-A headshells, it seems the guide pin is on the top of the new SPU-G but on the bottom of the SPU-A. Will an Ortofon AS309S tonearm accommodate both the new SPU-G and most recent SPU-A headshells, please?
