I have acquired 6 rek o kut turntables b12 h, with original micropoise tonearms. How good ( or bad) were these original tonearms. I have a number of projects ahead of me and wondered how much effort it is worth putting into the tonearms in trying to make them work well with the table. I did read the extensive rek o kut thread and it seems many use newer or different tonearms. Are they best suited for older heavier cartridges ? Any information would be appreciated. Thanks Norm
