Tuner memory
After decorating the lounge I have reconstructed my hi-fi stack and
rewired it so that the only item with permanent mains is the VCR - everything else goes through am electronic switch. I have now discovered that my Kenwood KT2060L tuner clearly has only a capacitor to back up the memory - it does not have a battery or use E2PROM - so when the mains has been off for a day or less it forgets. I have been thinking of replacing it for some time, possibly with a Denon TU260LII, but it would be no good if it suffers the same problem. Anyone know of any three-band RDS tuners that don't forget when the mains has been off for a while? Philips tuners of yore always used E2PROM, so I guess it may follow that Marantz do too. -- Woody harrogate3 at ntlworld dot com |

A capacitor back up can provide many months of memory, if required. Some older devices used either rechargable batteries, or, in some cases, lithium cells. In those cases, a couple of years is reasonable to expect. I have been thinking of replacing it for some time, possibly with a Denon TU260LII, but it would be no good if it suffers the same problem. **Denon make excellent performing tuners. Modern ones probably use capacitor back up and keep their memory for a long time (months, at least). However, your old tuner can be repaired for not much cash. -- Trevor Wilson www.rageaudio.com.au -- Posted via a free Usenet account from http://www.teranews.com |

Slainte, Jim The anecdotal evidence I was referring to is the failure which occurs when power is reapplied. The conventional wisdom in broadcast is to leave everything permanently powered whether in use or not, as the thinking is that stuff fails most commonly on power-up. I too have never seen any real evidence to this effect, but it has become enshrined in "custom and practice". It possibly descends from the days of valved equipment when the thermal shock of power-up could take out heater filaments. Large valves (especially transmitting valves) were left on standby with the heaters at just below dark red and no HT to avoid the thermal shock on switch-on. S. |

The nominal unit of energy is the Joule. Power is the *rate* of energy transfer/creation/loss. 1 Watt (power) is 1 Joule per second (energy per time period). Thus saying "watts per hour" implies "1 Joule per second, per hour", which may be gibberish as it is neither a power nor an energy. Thus the Watt-hour is also a unit of energy since it is the number of joules transferred/created/used if you use power at the rate of 1 joule per second for 1 hour. The common unit is the kWh. Hence it isn't clear what something like, "he consumes 400 Watts of electricity in one hour" actually means.

Setting aside the obvious stuff, like refrigerators, most items on standby consume less than 5 Watts each. Modern items consume less than 1 Watt. I have several itmes which I leave in standby mode and I don't feel guilty in the slightest. Here's why: It's August and we've just made it through the worst of a Sydney Winter (which, for thjose of you in the UK, is not like a 'proper' Winter at all) without using any room heaters. Not once. No air conditioning. Nothing. Just warm clothes. Mind you, it has been a relatively mild Winter, with no frosts (where I live) and typical pre-dawn temperatures of around 7oC. Given that previously, I would use around 12,000kWh per day in room heating, the 400 Wh per day for permanently powered stuff is small potatoes. I have shifted most of my lighting to regular fluorescent, or compact fluorescent, thus saving even more energy. Moving the (electric) hot water system inside and using a more efficient model has elicited rather spectacular gains in performance too. I now use around 20% of the energy I previously did for hot water. Frankly, I was stunned at the improvement and it has caused me to reconsider Solar hot water (very practical in most of Oz), given the high capital costs involved (I figure on a 30 year payback time). I would suggest that our domestic consumption is typical, even lower than average as our children have left home, so if more people turned off stuff on standby, the power saving would be very considerable. There is the anecdotal evidence that equipment left on standby or permanently on seems to be more reliable, but I'm happy to take that chance. **A common misconception. The killer for most permanently powered items are capacitor failures. Turning stuff off and on as required does several things: * Capacitors last longer. * The product is shielded from unnecessary spikes on the mains. I always turn stuff off (except for the obvious stuff, with clocks) unless I actually want to use it. -- Trevor Wilson www.rageaudio.com.au -- Posted via a free Usenet account from http://www.teranews.com |

Even leaving items like projectors plugged in can cost you a 200+ quid lamp - had a ten minute power cut here the other night (according to some of the clocks) and the next evening the PJ was dead..... Anybody ever made a successful claim on their power company for summat similar...??? |

If the appliance switch is simply turning off the incoming mains (the traditional way to do it), then pulling the plug or switching off at the socket is exactly equivalent. If the appliance switch works through some electronic function, then it isn't. But whatever the case, there should be absolutely no danger of damage. d -- Pearce Consulting http://www.pearce.uk.com |

Is there any truth to this? When I was at school (some time ago) appliance switches generally broke the mains input, exactly the same as using the socket switch or pulling the plug. Now they sometimes switch to a standby mode (as we have been discussing), or instigate a shut-down routine (computers, inkjet printers...) I guess you can't go wrong if you use the appliance switch, then the socket switch. Then remove the plug or not, depending if you're more frightened of an ungrounded appliance or a possible lightning strike. |
