Try advertising on here for someone to calibrate your table and arm for you. There may be someone within 100 miles who would be glad to find an audio buddy somewhat nearby. Also, if you were to state what table, arm, and cartridge you are using there may well be 'Goners who can advise you on line or by phone. Many of us have skills equal to or better than your dealer. And at least a few no doubt have better tools.
