maxg Posted November 23, 2004 Share Posted November 23, 2004 Alternative cartridges? Assuming this modded SME is a medium mass item: LOMC cheap - Denon 103D HIMC cheap - Denon 110 or 160 LOMC moderate - Denon 304 LOMC - pricey - Shelter 501 LOMC - more pricey - shelter 901 LOMC - very pricey = Shelter 90X LOMC - you have got to be joking - ZYX Airy / Fugi Giz a budget Pal-o-mine and we can come up with something I am sure (which, of course, you wont be - Shure that is). But, Fix the buzz first - I doubt it is the cart that is the problem (although it was dropped wasnt it...hmmmm). Quote Link to comment Share on other sites More sharing options...

Crushed by a 50# turntable, maybe something inside is discombobulated (but you'd think it'd hum all the time). Or it's feelings are hurt, that I could be so clumsy.

JBryan Posted November 23, 2004 Share Posted November 23, 2004 Fini, You'd have figured it out on the first track if the cart was actually damaged. Stick with the basics - its definitely a grounding problem. If your Mac isn't grounded properly then you should bypass the ground on it and find a suitable alternative. You may have an outlet close by that's been grounded to the plumbing or at least the conduits that will suffice. If not you can usually get a pretty good ground by simply connecting a wire to the existing conduit or running one to the nearest piece of plumbing. Barring that, you'll have to bury a rod outside and make your own ground. Bottom line - you need a ground for the cartridge (and possibly the TT bearing) if nothing else to bleed off static charges which could damage the cartridge. Have fun -Bryan Quote Link to comment Share on other sites More sharing options...
fini Posted November 23, 2004 Author Share Posted November 23, 2004 The Mac uses an un-polarized, 2-prong plug. None of the components have grounded power cords. Yes, the wall receptacle is grounded, so perhaps I will use a "power strip" with a metal chassis and accessible screw? Quote Link to comment Share on other sites More sharing options...

If the problem goes away, as I suspect it will, then you have to take the arm apart to see where the connection is failing. mdeneen ---------------- Mark, I tried it, and yes, the buzz goes away. It also goes away if I jump from that binding post ground arrangement shown in the photo, to the house wiring ground at the receptacle. Given the apparent complexity of this arm, and as long as I am not creating a dangerous or stupid situation (although that is what I am bet at), I'd rather go the easier route, which seems to me to be the powerstrip screw bit (or replacing the Mac cord with a grounded version). Do I really have to disassemble the arm? Quote Link to comment Share on other sites More sharing options...
Allan Songer Posted November 23, 2004 Share Posted November 23, 2004 You do not need to rewire the arm--I used that arm on and off for years and I doubt anything has gone haywire inside the arm. I will send pics on how I ground my table and arm and if you follow muy lead you will not have any problems. As far as cartridges go, it all depends on what your budget is. $100? $300? $500? Are you brave enough to buy a SECOND HAND phono cartridge? I ALWAYS buy them second hand--you get REALLY good deals that way! Quote Link to comment Share on other sites More sharing options...
fini Posted November 23, 2004 Author Share Posted November 23, 2004 Allan, No specific budget on a cartridge, and second-hand is fine. It's the stylus you want to get new, right? Quote Link to comment Share on other sites More sharing options...
Allan Songer Posted November 23, 2004 Share Posted November 23, 2004 Any cartridge I will suggest will NOT have a stylus that you can replace "at home." It's a crapshoot with used cartrdiges, but I have been burned only one time . . . Quote Link to comment Share on other sites More sharing options...
fini Posted November 23, 2004 Author Share Posted November 23, 2004 Are you saying you don't think it's pretty? Dang! I was hoping to sell the idea to Juicy Music... As a make-shift solution, I have run a separate 12 ga. ground wire from the cover screw at the wall receptacle to the "ground box" (patent pending). I still get a miniscule hum, plus a static pop if I've been shuffling my feet on the carpet. The current weather conditions seem pretty good for static electricity. That problem seems to be minimized if I touch the receiver frame before touching the headshell. Maybe I eat too many electrolytes or something. Could be the ground coffee....
