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.

As someone who has heard the stock SL-1200MK2 wiring, I can say with certainty that the "darkness" issue is, in fact, the stock wire. It's the weakest link on the table by a long-shot.

I know conventional wisdom with regards to the KAB upgrade path has been "do the fluid damper first", but I would say that if you have a MK2, do the rewire first!

Absolutely right. Those who bought M5Gs wonder what all this "darkness" fuss is about. We never heard it because the M5G and GLD editions have factory upgraded tonearm wire. But if you start with a mk2 or mk5, your first upgrade *must* be the tonearm wire, or it will compromise the benefits of the other improvements until it's addressed.

This may be why some owners find the installation of an RB250 or RB300 to be such an improvement and revelation, where others say "meh" and return to the original arm. The improvement may have more to do with the wiring than migrating to a straight arm with integrated headshell.
Just a query on the SL-1200 tonearm you mentioned. Do you happen to know if it is compatible with the Michell GyroDec?
