New upgrade alternatives for the Technics SL12x0

Up to now, if you wanted to do something about the Technics SL12x0 series tonearm, you either got KABUSA's fluid damper or the Origin Live adapter armboard, enabling mounting of most Rega-mount arms (including the Origin Live line.

If you wanted a better power supply, you could get the one from KABUSA.

Well, there's a new vendor in the UK, Sound Hi-Fi, a comprehensive British high end vendor who also offers some interesting modifications of the SL12x0 series here.

He has armboards for SME and Jelco tonearms. Why no Rega? Owner/operator Peter Cawley doesn't feel that the Rega is a particularly good match for the Technics.

Consider this: When Panasonic released the 1st gen SL1200, they also offered the SL120, the same turntable, but with no tonearm. It came with an armboard for the SME Type III Improved. SME was probably the number one tonearm choice for Technics take-no-prisoners pro model, the SP10.

Peter also likes Technics/Jelco matchups very well. So if you can get ahold of an Audioquest PT6 or PT9 ... Here's a 9-page thread from mostly last December where an SL1210 enthusiast (who already had several KABUSA mods) introduced Sound Hi-Fi to the Analogue part of the Art of Sound HI-Fi forum in the UK. During this thread he upgraded to a Jelco arm and the review is pretty interesting.

Notice that Peter has his own external power supply, 78 rpm mod, and three different aftermarket feet including the Isonoes. His type 1 feet are actually just Foculpods. Also, his turntable mat is sourced from Herbie's.

Marco's review in this thread mentions the Technics' tonearm's persistent upper midrange "spotlighting", something I usually call "glare." Following that hint, I wrapped some very thin, lightweight plumber's tape (the Teflon kind for sealing threads) around my tonearm including the headshell joint, and voila! The midrange calmed down and with it I got a more relaxed sound with better ambience retrieval and a fuller, yet better defined bass.

Anyway, I recommend you follow the links and do some reading/surfing. I found it quite enlightening to find another pocket of SL12x0 enthusiasts and an alternate source of upgrades and modifications.

Also, notice that Peter sells Avid, SME, Clearaudio, and Marantz turntables, and SME, Jelco, and Hadcock arms, so if he has an axe to grind, it's a pretty broad one.

Edo_musica: thanks for posting that link but please keep this in mind when reading Tone's publication.... He doesn't like KAB because he won't send him a free review versions and the reviews in the past of the Technics SL1200 was done with an Audio Technica deck that looks like a Technics.

Peter isn't a fan of the Rega based on his cart choices if you notice he recommends arm/cart combos and I agree, I tried running a Shelter 501 mk2 on a RB300 and all it did was shake the arm to death because of the short stiff canti.

Plus for people running heavy Denon Carts Jelco has higher mass arms that work better with this type of cart then a lower end Rega.

I also think Rega's were the only thing going in the past in the Low dollar category and now you have Jelco in the mix which provides another step up or lateral (except people have recommended rewiring them)

Thanks for bring this up Johnny. I have been reading about these guys in the UK for a few weeks now. My interest is in the 1200/Aquest PT-9 combo. I sold my modded KAB SL 1200 this winter (they go very fast) and got a VPI HW 19jr with the PT- 9 arm. It is a nice table and the arm is great but I am having a hard time dealing with the speed instability of the belt drive in comparison to the dead nut speed and torque of the Technics. Although the Technics arm is very underated and I miss the removeable headshell, the Audioquest/Jelco PT-9 is a notch up the tonearm foodchain to my ears. I know I could buy the SDS speed controller and probably solve this problem, but at $1,000 I'll pass for now. After reading about these guys overseas mounting the PT-9 to the Technics deck and the great results they were getting I felt this was the way to go. Although I love dealing with Kevin at KAB, I heard that these guys are top shelf also. So at some point soon I am going to throw the PT-9 on a SL 1200 deck. I am really looking forward to it and will let you know when I pull the trigger.

Johnny-
You mentioned wrapping teflon tape around your arm. How did you actually get it to stay put as it has no adhesion?

I use garden variety teflon pipe thread tape like this. I just wrap the last bit perpendicular to the arm shaft and press hard to make it stay put.

It's not that Marc Phillips doesn't like KAB; KAB won't deal with him because of things he's written about the Technics (they were opinions, not reviews) for a couple of online audio mags over the last few years.

They aren't reviewing an Audio Technica PL-120 instead of the SL1200 Mk2; they're reviewing both. Publisher/editor Jeff Dorgay did a very favorable review of the PL-120 a few issues back and Senior Ccontribing Editor Marc Phillips is doing an ongoing evaluation of the SL1200. He has tried at least 20 different cartridges in it and is now looking into installing an SME V on it. His most recent article about it mentioned that the Ortofon 2M Blue is a good match but he's bothered by a persistent darkness to the tonality and a narrow soundstage. That's why he's looking at the tonearm upgrade next. His main deck is a Michell Orbe with SME V.

If the arms are about equal quality but the Jelco is a better match, then it's an improvement. Of the two Jelco arms Peter offers, one has a foam-damped tube and a straight, one-piece tonearm with an effective mass of 11g. The other is an S-shape arm with detachable headshell, oil-damped bearing, and effective mass of 18g. Peter recommends the heavier arm for the DL-103 and the lighter arm for typical medium-compliance cartridges.
