Few questions regarding second hand arms/Technics Mod

Hi, after looking around I thought it would be a nice idea to go and get a Rega RB-250 arm with an Origin Live Arm Board and fit it to my technics sl1210 mk2. Any sort of things I should look out for? Or any tips? I know most bearings in the arms of technics sl series if brought on ebay are crap, I had a few of these. I'm also toying with the idea of getting some Grado DJ200's or 100's styli.
I personally think the stock technics arm sound awful.

If I go ahead I will ebay the 2 Technics arms complete with base and 2x Ortofon Concorde Night Club Eís, this should cover few things anyway.

I can't believe that, sad isnít the word! All the dealers around here including retailers selling Linn are very much into their turntables and know a lot of stuff., always very knowledgeable and helpful (The smaller stores) I havenít had the time or money to go into these sort of shops for at least a year now though.
Also check out the reviews about the modified rb-205

I will have a stock 250 if I go for one but the upgrade potential is real nice it seems, also it seems to get better reviews than the pricier RB-300

Thought so. No Linn comes cheap, and wayyyyy out of my budget. If I had the cash I would go for a new top line SME arm drooollll , I think GSA or Shortey uses them on theyr installs.

Rega Silver tone arms with Grado Prestiege Gold cartridges, and they sound amazing takes about a week or 2 to break in depending on how many hours you use them at first, i am ordering shortly, the Rega silver MK2 arms for my other 2 turntables.

I am a dealer for the Origin live products so if guys want these products i can offer them to you.

I have used the SME 3009 OR 3006 cant recall the old model # tone arms in a few situations, and dont like them, with a floating suspension and a counterweight on the line swinging, it tangles up and will throw off the tone arms tracking and will effect the way it will track in the groove, so it will effect the quality of your music and system playback. This is why i did not go for the Rega Encounter arm, for the same reasons i dont like the SME, the Encounter is even more superior to the Silver or SME products, which the SME tone arms are not even made anymore,but i didnt go for the Encounter because the Encounter aswell offers this tone arm with the counter weight on the string like the SME but the encounter sounds rediculous.

For a standard home audio enviorment where the turntable is on a flat surface that does not float, they work well but not in a situation when the turntable is on a floating base with rubber band suspension. But i still enjoy the Rega Silver Tone arms better for music playback over the SME any day of the week

Good to know! i was planning on buying the adapter plate and possibly some isonoe feet directly from OL. i'll send you an email for pricing.

btw, does anyone know how well the RB250 lines up parallel to the platter with the OL mount and standard Technics rubber mat? i was thinking that a VTA adjuster might be required, but it doesn't seem to be necessary in the photos. in fact, it almost looks like the mat could stand to be just a hair thicker.

Sugest you use a VTA adjuster to set this up, because you can set these tone arms up with different adjustments and each way it will sound different, so you can try it in different weays to tune it the way you like

VTA adjuster

I bought a VTA adjuster when I got an RB250 and OL armboard for one of my 1210s. I ended up not using it because without it, the arm sits at just the right height, parallel to the platter. With the adjuster, the extra height pushed it up a bit too much so the arm was at a bit of an angle.

unless you have audiophile soundgear its not going to be much of a noticable difference especially on a club system at higher volume with an arm like a rega or sme

the technics arm is pretty good with a grado cart

If you're going to keep the original rubber mat (good man - massive improvement right there - I can't understand why anyone would remove it...) you'll need a VTA adjuster.

With your average slipmat and no VTA adjuster, the arm will be parallel; but with the mat, you'll need the extra height afforded by the VTA ring.

The difference on kick drum is astounding. I would suggest to anyone that can't hear it that they might want to get their ears syringed...

the rega arms sound better and much clearer and musically sure footed than the technics arm.
the origin live arms dont really do it for me, i use michell tecno arms.
by the way the the new sme 3 series and the iv and v do not use thread bias systems and work fantastically well on technics 1200 decks but they are all very expensive. and armboards are hard to come by if you cannot make your own.
you should all remember the arm has more influence on the sound quality than the cartridge in terms of musical information being retreived.

i have played my modded decks to lots of people and taken them to clubs and sound men and dj's are always gobsmacked at the better sound of the upgraded decks.

i would not use a linn arm on a dj deck the arm bearings are waaaay to fragile a big no no and a very expensive mistake.

stick to rega / michell or go hi end with an sme 310 or series iv. the v is overkill.

this is for my listening rig - all tube gear, so yea, the little things are going to make a noticable difference...

also good to know your opinion. i have not personally heard the OL arm, so i have nothing to base their claims on. i'm planning on sticking with the stock RB250. down the road, i will probably do a Cardas rewire and go with a new counterweight setup.

I might be wrong but...That's a bad mod! You are still using the nasty technics bearings and arm. Also those bearings should be done to a precise tightness and Iím talking microns.

Regarding bearings: Technics SL-1200Mk2 arm bearings have a tolerance of ± 0.5 microns. Bearing friction is 0.007gr. Do you really think a Rega RB250 or RB300 (I own/owned both, btw) has better bearings?
You'll might find the Regas better sounding, but that's another story.

Are you familiar with the "Linn swing test"? You remove the couterweight, place the arm hanging vertically on e.g. the end of a table, give it a light push, and count how many cycles the arm swings before it stops.

I had a little Rega RB300 vs. SL-1200Mk2 arm shoot-out a while ago:
Rega RB300: approx. 30 cycles (I don't remember the exact number). That's considered to be very good.
Technics arm: I stopped counting after 250 cycles...

That arm modification is utter cr*p, though.
