It is on a shelf of a buit-in cabinet. It is a pretty solid cabinet, built of 3/4 cherry plywood,the shelves have a solid cherry front edge, and they are dadoed,screwed and glued into the sides, which are screwed to the walls that surround the cabinet on 3 sides. The turntable used to sound fine, but the sound deteriorated to the point where it is awful. The Amp is on a shelf under the turntable, and one of the speakers is on the shelf above. The other speaker is on the top shelf of an identical cabinet in the other corner of the room.
I used hedphones to eliminate speaker contribution to the problem- and the same rumbly distortion was present. I pulled the cartridge and examined it and visually it was OK- no obvious signs of damage and the cantilever was straight and seemed to be in the right position and moved normally. It did not skate on records and tracked normally. I get sound from both right and left channels, but it is distorted, like being played through blown out speakers. I have read the "suspension" in the cartridges may "dry out"-could that be the problem here? Is there any way to check or repair this? I don't have a microscope to look at the tip, and wouldn't know what to look for anyway. I have seen a site (aminaaudio.com, aka Modular electronics, Inc. ) that says they rebuild these to be the functional equivalent of an MMC4 cartridge. I am aware that Soundsmith sells a new replacement for the MMC4 for $149. Any thoughts on either alternative? Anything else I should check before assuming my cartridge is a goner?
