While sorting out the loss of one channel, Michael Yee of Nova Phenomena suggested I lcheck the leads from my Dynavector 17D3 cartridge. I touched both + and - leads at the same time on the missing channel and Voila!! music! I have no idea what happened or why. Then i got out an old (25 year +old) cartridge demagnetizer and did its thing. Good Grief!!! Amazing new clarity! I'd noticed misic seemed to be getting smeared. Instant cure. Great sound with the Nottingham 294 table and arm. I'm guessing the cartridge had +/- 500 hours use. The Dynavector distributor (a great guy and good to deal with) thought that Dynavector's fluxbuster obviated the need for demagnetizing. Not so with mine. How often should a cartridge be demagnetized?
