Put heat shrink on the arm.

Tubes & Klipsch!
Just take head shell off, slide heat srink on up on arm and srink? What does this do?

Heat sHrink tubing, once sHrunk, should aid in dampening the tone arm.
Some folk feel the tone arm is susceptible to picking up resonance so this should act as a type of shield and damp the arm.
Simplified, think a rubber handlebar grip on a vibraty motorcycle compared to just gripping a bare bar.
That's over-simplifed and not a 100% accurate description but gives you the gist of it.
Careful not to heat the tone arm too much as you may melt the insulation of the internal tone arm wires, then you are facing a tone arm re-wire if you damage the internal wire shielding.

You can also try wrapping it in plumber's tape- rumored to have the same effect and easier to do and un-do.

Yes the plumbers Teflon tape made a slight difference on the arm of my SL1500 Technics. It takes a bit of practice to get it wrapped neatly, but the good thing is you can wrap and unwrap it till you get it to look good. I found that if you keep it tight buy putting a bit of a pull on the spool of tape it wraps better and tighter.

...and don't forget to figure the added weight into your resonance calculations.

Just a update:
Received both items today!I really won't get a chance till the weekend to give it a good going over but I will give my review then.
:thmbsp::thmbsp: for PCNation! Super service super price and super duper fast shipping!
Finally had a chance to set everything up and give it a go......must say I'm very impressed with the SL-1210M5G and the AT440MLa combo. They seem to be made for each other.:thmbsp:
Setup was pretty straight forward. But as usual mounting the cart was a little tough.....or maybe it's just my old age that makes things a little tougher than it use to be....
First piece of vinyl to go on was the "The Beatles" Original Recording Master White album. What a joy it was to sit back and listen to some good old music! oh, and the sound was fantastic.:yes:
I'm really going to enjoy this new addition to my setup for many years to come.
The only issue I'm having so far, not the fault of the TT or cart, is LF feedback when playing at loud volumes. I included a few pics of my setup and you can see the table with the TT is relativity close to the speakers. The speakers are AR9's and they can really pump some bass! Until I can find a better way to isolate the TT I'll just have to keep the volume down.
Anyway, anyone thinking of getting a new TT at a moderate $$$ will be very happy with the SL-1210M5G! And I think it's one sexy looking piece of equipment.
I also included a pic of my favorite TT......Wurlitzer 2200

Before playing loud remove the Dustcover that will help to reduce feedback.
Looks good...real good! and that R-2-R OMG so sweet
Please list the equipment I am dying to know the rest of the setup.
Nice system! ...but yeah, the speakers are almost coupled to the walls as far as proximity. I can't see behind them; but, I would imagine there are no bass traps behind them. So, essentially you've got the corner placement of the speakers intensifying the amount of bass energy that's already coming from the spkrs and the TT is sitting right in that field. As good as the Technics is, I'm not surprised you're having a bit of an issue.
But, you've got what appears to be a brick hearth stretching out into the room. You could try a small rack in front of the TV (low enough not to interfere with the viewing) and place the turntable there. Not good if you've got pets or small kids; but, that would definitely get the TT out of the "bass zone" and anchor it to something with more mass. Or simply moving the speakers out in the room a bit, might help...
...just a thought...

Here's the list:
SL-1210M5G TT
AT440MLA cart
Carver C-19 preamp
Carver C-9 Sonic Holography Generator
2 - Carver TFM-45 amps. (One is at Rita's Vintage Audio Repair for rebuilding, the other will have the same done)
Carver TFM-25 amp.....might throw my extra subwoofer on it just for kicks!
AR9 (1980's originals) speakers. The surrounds have been replaced and XO have been rebuilt. Each speaker is vertically biamped to the TFM-45's
Sony 5 disc Cd changer
Audio Source EQ-200 graphic equalizer
ReVox B77 RTR (this thing sounds fantastic!)
Nothing special, but sounds very good.:yes:

Very nice set up you have there. I just ordered a SL-1210M5G myself.
Quick question. Did your M5G come with hinges or did you install them after the fact? It looks like is has hinges in the pictures.

The AR9's are designed to be placed against the wall, I know that sounds odd but that's what AR recommended. Maybe I could pull them out a bit to reduce the bass output.
here's a excerpt from the manual about speaker placement:

Xmas111: very nice setup! I'll bet it sounds fantastic 
I think those wood floors are vibrating. I'd try to set those ARs on some granite blocks or something very dense. I had the same problem with wood floors with my old JBL 4311s. I hung them on the wall near the ceiling and the feedback problem stopped.
Also, I found that if I put the dust cover down it helped deflect the bass. But that was with an old Pioneer PLA-35.

Man that is a nice setup. :tresbon:
If removing the dustcover does not eliminate the LF feedback and I know they are a little pricey but well worth the investment the Isonoe Footers & Sorbothane Boots...less the glass discs, at KAB
I have my table right next to my speakers and pushing an enormous amount of power and since the isonoe system I can not get it to feed back.

My bad! LOL! I was looking at the wrong pics. (...aging is a terrible thing)
Interesting suggestion about the dust cover. I never have mine on when playing. I may have to test that out. I'll have to go with just about all of the previous suggestions of anchoring the spkrs and controlling floor resonance and/or using footers or some type of isolation platform. I think I was looking at AutoBot's rig. Those spkrs are huge! They'd tear my listening room off from the rest of the house. :thmbsp:

The Isonoe system it makes a dramatic improvement with low level detail retrieval even at low volumes.
The system makes it easier to get the table level (perfectly level) and it stays level.
It was one of the most noticeable tweaks I did, was it a budget tweak? not really, but was it worth it? absolutely. :thmbsp:

Thanks xmas111, I ordered the hinges from KAB. Now I just have to sit here until everything arrives.
<sigh>.........sitting here waiting.
Also have to make sure the SL-1301 does not find out it is about to be retired. I don't want it taking revenge on my LPs.

I have been using a Technics SL110 with a SME 3009 tonearm and a TOTL Audio Technica cartridge for the last 5yrs. In that time I have also had an Oracle Delphi, a Systemdek and a Rega 2 . Faced with the need to sell a few I carefully evaluated and decided to keep the Technics/SME combo as frankly it was the best sounding of them all. My question is - why do I not find any other posts relating to this TT? Are they that rare? I would love to hear from some other owners of this TT. I have the original manuals for the table and the tonearm plus the mounting template. Gladly provide scans if anyone is interested.
