Jelco TS 550S Tonearm for Thorens


The Jelco 550S, new to the market in January 2018, is Jelco’s latest in their tradition of making tonearms with exceptional value. Note there is NO drilling, grinding, or cutting the metal subchassis involved! The Jelco 550S is a drop in fit.

Note: For your safety, owners of 14X models with auto-shut off should seek a qualified professional to defeat and circumvent the auto-shut off. The rest of the modification is very DIY.

The Jelco 550S, new to the market in January 2018, is Jelco’s latest in their tradition of making tonearms with exceptional value.  Like their previous 750 series arms, this features a universal headshell, easily adjustable VTA, and the ability to add damping fluid.  Unlike the 750 series, it features a single counterweight that can account for cartridges in a very wide weight range. Most 550S will be sold with a budget headshell, but I am including at no extra charge the HS-25 magnesium headshell with adjustable azimuth. Like other Jelco arms, this leans on the side of being heavy in mass.

The included custom cable, sourced from the UK, is specifically designed for suspended decks. It features Mogami Mini Starquad Tonearm cable, an angled DIN connector and Starline RCAs. It also has dual grounding. I’ve been using this cable for two years on all of my Jelco arms; it’s an exceptional cable, and it’s included at this price! Most angled DIN tonearm cables made today are too thick/stiff for suspended decks.

The US-made Jelco armboards are ONE PIECE of high quality machined aluminum, brushed and anodized.   Check out the exceptional fit and finish using the magnifier. They look amazing.   Included with your armboard are three stainless steel screws for attaching the plate to the table. You can use the existing Jelco nuts/washers to attach the arm with three shortened screws I provide.

From Jelco:

“9 inch oil damp static balance type with headshell

Simple mechanism is excellent for sound reproduction
the tonearm geometry allows for a Baerwald amendments which is IEC recommended
new type of counterweight equipped to handle 17 to 34 gram cartridge with headshell installed”
