You weren't specific as to which 'table and tonearm you're refrerring to; the Alexandria came with a stock arm that was made by Sumiko. This arm was difficult to adjust and a bit flaky.
The Delphi was available with an optional arm from SME, they called it the SME 345. SME built this tonearm using the detachable head shell from the series 3, the Series 4 bearing, and the Series 5 silver litz wiring. This arm is very easy to make adjustments, going by memory Oracle offered this arm about 15 years ago, and they still sell it today. Regards, Jeff
