Maybe in your ficticious example I would be nuts, but in my real life, I replaced a 15 year old refrigerator with a $499 new one, and my electric bill dropped about $40 per month. That's complete payback in about one year, which is at least as good of a return on investment as most people get from buying home insulation. You completely panned the idea of the original poster buying a new refrigerator, saying, Getting a new fridge is almost as silly as getting a $5K power regenerator from an audiophool shop. My point is that getting a new fridge depends on the state of his old fridge. I fail to see how overpriced audiophile power regenerators are relevant to that. -- TiredLegs TiredLegs's Profile: http://forums.slimdevices.com/member.php?userid=6201 View this thread: http://forums.slimdevices.com/showthread.php?t=39691 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Annoying tick when fridge turns on/off
The problem here is simple electricity. If everything is plugged into the same fused circuit (the fridge and stereo are on the same panel breaker) that is the first problem. The fridge compressor draws large amounts of current at start-up no matter how big the capacitor. Compressor/motor noise rides back out the line as the current rushs in, so anything on that same breakered line sees noise. Second problem is your line level RFI/Surge outlet box probably uses MOVs for surge and other filtering devices that need a proper ground to work. So it is useless for both RFI and Surge Protection without the three prong ground! Without a proper ground all it is is a master switch and a very expensive extra outlet strip. First try moving the system to another outlet that is not on that same breaker. If this does not help, move system to an outlet on the other hot leg for this should isolate it from the noise source. You could also have an electrician install a properly grounded outlet and see if your RFI/Surge protector can filter out the noise. Two quick question: Does your fridge have a two or three prong plug. Does the outlet the fridge plugs into have a three hole outlet and is it properly grounded? -- iPhone iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=39691 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

It sure isn't a way to save any money (how can you save money by spending money?), and it isn't a green idea either. That's like saying you can't save money by insulating an old home. In this case, it really depends on the state of his existing refrigerator. If it's old and energy inefficient, a new one could pay for itself in electricity cost savings in a couple of years. Whether or not that would be green is a separate issue from the economics. And whether or not that would stop the annoying tick is a whole different matter. One way to solve the tick problem might be switching to battery powered amps, such as those made by Red Wine Audio, but fixing the cause of the tick is probably a more cost efficient solution. -- TiredLegs TiredLegs's Profile: http://forums.slimdevices.com/member.php?userid=6201 View this thread: http://forums.slimdevices.com/showthread.php?t=39691 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

If you replace a refrigerator you spend $800 or more to reduce your electric bill by $5 per month, plus you send a working refrigerator to the scrap heap. When you insulate an old house, not only do you start saving money on your energy bills, but you increase the value of the house. The insulation pays for itself in a relatively short period. When you buy a new refrigerator, is gets older and lower in value everyday. It might pay for itself in the power savings in about 30 years. Spending $ on a new refrigerator because the old one makes clicky noises in your audio system is just plain dumb. It is almost but not quite as dumb as spending $Xk for a power line regenerator for the same reason. Switching to battery power because the refrigerator makes clicky noises in the audio system is still more silliness. Do you always dance around problems this way? You are a marketer's dream come true!

S2K;238292 Wrote: Whenever Im listening to my Transporter I hear a very irritating tick in the music when my fridge is switching on or off. The Fridge and my audio equipment are on the same power group. The audio is connected to a power block (don´t know the proper word) which is supposed to filter the mains for EMI and over current. It isn´t connected to a wall socket with grounding though. Funny thing is that it only effects the transporter. When I listen to Radio it doesn´t happen. Someone said that the fridge has a defect capacitor. What can I undertake to get rid of this very annoying thing? Get a new fridge. ;) Seriously, ground your outlets.. Ungrounded AC power is bad news. Back to the fridge, if it's older than 10 years, you really should consider a new one. There have been huge advances in cooling efficiency in the last few years. You could save $$ a month in electricity. -- SuperQ SuperQ's Profile: http://forums.slimdevices.com/member.php?userid=2139 View this thread: http://forums.slimdevices.com/showthread.php?t=39691 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Annoying tick when fridge turns on/off
The noise comes from the compressor motor. When the fridge turns on there is a sudden, large inrush of current because the motor looks like a huge capacitor. That surge puts a transient spike on the power line that is finding it's way into your system. The best thing to do would be to separate the power circuits for the audio and the fridge. If you can't do that, you might try putting a line filter in either the audio or the fridge's power or both. No, I don't mean a $5k power regenerator that the audiophool shops sell for this sort of problem. I mean line filters like these: http://state-electronics.com/corcom/corcom2.asp maybe the K series parts. Surplus dealers often have these sorts of filters available for very low cost. Specs are not critical for your app. Just make sure the filter you get is rated for enough current to handle the load you will apply.
