I have not experienced any changes in the sound quality of the 3009 series II during the last 10 years. In fact, the sound has improved in the last 2 years. The cartridge used for the vinyl LP's has improved my enjoyment of vinyl considerably. It is one of the best cartridge.
My other units are the vinyl LP's I pick up at thrift/second hand stores (usually 45rpm's but I bought a few LPs last summer). The LP's all have new tonearms with genuine belt/pulleys. The units are given a good cleaning and varnish and a good coat of shellac. The LP's are played in the crates. The 3009 SII is placed in the top center and is turned at about 45 rpm for LP's. I have never heard a scratch on any LP's I have played.
I use a vintage phono stage for all of my cartridges. I am not a big fan of high end electronics and the best I can do is the Denon AVR500. I have not been able to fix the phono preamp for the 3009 SII so I use a 100 watt. The Denon has a 500 watt preamp and uses the same phono stage. I have had the stage for about 8 years and has done well. All the cartridges are used and are in the same condition as when I picked them up. All except for the phono stage.

In the 3009 III the rider weight on arm 5 is less than the rider weight on arm 1. This was done to compensate for a bad sound quality using the 3009 III. This was all compensated for in the 3012 III and the rider weight on arm 5 is more than the rider weight on arm 1. The bigger the rider weight on arm 1 the better is the sound quality.
The 3009 SII is the first new arm from Technics. It is the successor of 3009 Series I and 3012. Series I was the most popular of the 3009 Series. It was produced from late 1978 until mid-1983 and was offered with 6 different counterweights (for g = 0.65, 0.98, 1.31, 1.61, 1.91, 2.27g) 827ec27edc
