Cartridge issues are needling a turntable owner

Q: I decided to pull out my old Technics SL-B20 turntable and hook it up to the phono input on my Pioneer SC-25 receiver. Unfortunately, hardly any sound comes out of the speakers. I'm guessing that this is because the receiver doesn't have a "preamp" for the turntable.

Do I need a phono preamp, or would I be better off purchasing a new turntable with a built-in preamp? I will use it for a few hours a week until I build up my record collection again.

A: Because your receiver has a phono input, it likely already has a phono preamp. Typically, any input labeled "phono" has the extra amplification and equalization needed for most phono cartridges. I checked to make sure, and your SC-25 receiver does indeed have a phono preamp.

The likely culprit in your case is the cartridge. They are mechanical components that break down over time, and if you have not used your turntable in a long time, that's where I'd start my investigation.

First, make sure the tracking force is set to 1.5 grams. Do this by turning the counterweight to balance the tonearm so it is level. Once it is level, set the index ring to 0, then turn the weight so it reads 1.5. That might solve your problem.

If it does not work, try a new, inexpensive phono cartridge to get you by for now. Your turntable requires a P-Mount cartridge. The Audio-Technica AT92ECD can be purchased for under $20 online. Once you build up your vinyl collection, you can shop for a better turntable.

SVS speakers have long been known for incorporating extremely high-performance subwoofers into units that are very affordable. The company also applies its high value/high performance philosophy to home theater and stereo speakers, with admirable results.

The $999 SVS Prime Satellite system combines a subwoofer with five speakers. The speakers are a bit bigger than the teacup-sized speakers found in most small systems, and it makes all the difference in the world. The larger woofers reproduce the midrange much more accurately than a tiny speaker can, creating a much fuller sound.

The Prime Satellites come in either a simulated black ash finish or a gorgeous high-gloss piano black that costs $200 more. After seeing the piano black, I'd go that route, but only if you keep in mind that the extra money is for an enhanced appearance only, not better performance.

The sound of the Prime Satellite system is tremendously clear, dynamic and detailed, with impressive punch from the 300-watt subwoofer. It was driven by a modest Onkyo receiver but still attained a very high level of performance and sound quality. I was told by company reps that the designers wanted people to be able to buy the speaker system and combine it with a $300-$500 receiver and get truly great sound. They have succeeded.

I will have a review of the SVS Prime Tower speakers in an upcoming column.
