I was so happy that the owner's manual was available. It is well written and helped me to use the radio/CD player/recorder without problems. Thanks for making it available.

I highly recommend this.

Thanks so much for the Owner's manual for my Sony PS - FL1. I had purchased the turntable off of eBay. It came in and looked great. Packed well and appeared to be great. I balanced and aligned the tone are and hooked it up. When trying to play a record the tone are would move to the right place and just before it would drop to play it moved back off the edge of the record before touching down. I searched the net for an answer to this issue. No luck. Then I purchased the owners manual and sure enough there was a place to adjust where the stylus touched down. That adjustment solved the problem and saved me a $35 feet to have the player checked out. The manual is well written and easy to understand. It is a must have for anyone with this front loading Sony turntable.

Some years back I pruchased a Sansui G-9000. I had it cleaned up and a problem with the left channel repaired. When I got it back I hooked it up to my tape decks, turn tables, TV and it played great. The only thing I was not really satisfied with was the performance of my Graphic Equalizer. I purchased this owner's manual had poured myself a cup of coffee. The manual is well organized and written in plain language. It also contained the solution to my dissatisfaction. By using the preamp connections coupled I was able to run everything through my graphic equalizer and now enjoy the full potential of my complete system.

An excellent service for the price, however, it would also have been handy if the troubleshooter pages were included. The manual is only sent in the language of your country, thus it looks as though there are some pages missing. Otherwise highly recommended.
IMPEDANCE (continued)
one 8 ohm enclosure, you know you can add one more 8 ohm speaker safely (8 divided by 2 = 4). Although much less common, you could also add one, or even two, 16 ohm cabinets: two 16 ohm cabinets in parallel have the same total impedance as one 8 ohm speaker. To get the most efficiency out of your system with the fewest cabinets, your best choice would be to connect two 8 ohm enclosures. Since you would be driving two cabinets of equal impedance, each will receive half the power your amp can deliver. If your amplifier delivers 200 watts RMS at 4 ohms, then each cabinet will receive 100 watts RMS maximum under clipping. (Clipping is the point where the power amplifier runs out of headroom and begins to distort.) If you had four 16 ohm enclosures, each one would receive a maximum of 50 watts RMS under clipping. Continuous clipping is very harmful to speakers, especially in a bass system: the lower the note, the longer the duration of DC content in the clipped signal. To understand what happens under this condition, remember the example of what speakers do when a 9 volt battery is applied to them. Now imagine what 20 or even 50 volts would do at the rate of 40 times per second! The results can be overheating, disfiguring of the voice coil, overall fatigue, and�eventually�complete failure.
TROUBLESHOOTING GUIDE
�I�m hearing unwanted distortion through my cabinet.� This could be for a variety of reasons, but is probably being caused by one of the following three sources: 1) the amplifier, 2) the cabinet�s woofer(s), and 3) the cabinet�s tweeter. The best way to figure it out is to try and isolate �the big three.� If you have access to another (working) bass cabinet, hook your amp up to it. If things are still distorting, it�s probably your amp. Consult your amplifier owner�s manual for troubleshooting that piece of gear. To determine whether the distortion�s coming from the tweeter or the woofers, first put your ear up to the cabinet, play some notes, and see if you can hear where it�s emanating from. If you can�t quite narrow it down, try turning the Tweeter Attenuator control all the way down (counter-clockwise). When this control is all the way down, the tweeter is effectively �off.� Play some notes�if you hear distortion, you know it�s not the tweeter (see next paragraph�). If you don�t hear any distortion with the tweeter off, try turning up the Tweeter Attenuator. It may be that you just need to find the optimum tweeter level for your bass, amp, or style of playing. If the tweeter distorts no matter what level the Tweeter Attenuator control is set to, it�s probably best to call SWR�s Service Department. The number�s (818) 253-4797. If the tweeter�s off AND the amp�s okay, and you�re still hearing distortion, there may be a problem with your woofer(s) and/or the cabinet�s internal workings. Inspect your woofers� cones for folded edges. There�s a very slight chance you have a defective woofer. Or, you may have blown one or all of them by driving them too hard. Speakers that have been overdriven are easy to detect, and generally do not fall under a manufacturer�s warranty. You should call SWR�s Service Department to determine your next move. The number�s (818) 253-4797. �I hear intermittent distortion and/or crackling coming from the cabinet.� This could be due to a bad speaker cable, or a bad speaker cable connection. First, make sure the cable is securely connected to both the cabinet and the amp (or other cabinet). If you�re using more
