Rooster_Ties Posted May 23, 2003 Report Posted May 23, 2003 (edited) Even if I wanted to argue with you about that, how could I? Where would I even begin?? (Not that I want to argue about it, mind you. ) Me?? I often forget to turn off the Memorex "clock-radio/cd combo" player (that I got at Target on close-out after Christmas, for only $10!!). Doesn't seem to affect the sound quality either way, come to think of it!! Edited May 23, 2003 by Rooster_Ties Quote
J Larsen Posted May 23, 2003 Report Posted May 23, 2003 I see RoosterTies wants to test me. Well, RT, you might want to know that leaving your Memorex radio on when not in use can eventually result in the emmission of a high-frequency radiation burst which will destroy all of your electronic equipment.

sidewinder Posted May 23, 2003 Report Posted May 23, 2003 Sounds like there are quite a few varied opinions on this issue - all of them quite valid. Ultimately you must go with whatever works for your particular system implementation. For analogue circuitry, the switch-on oscillations are not really an issue. Transistor noise though (attributable to random, thermal and shot noise sources) does require time to settle and is minimised when the ambient environment is nice and steady. The cumulative effect though depends on the spec of the transistors, the regime in which they are operated and the design of the stages. Implementation dependent so go with what your ears tell you ..

Clunky Posted May 23, 2003 Report Posted May 23, 2003 my fairly basic Marantz set up sounds warmer (better) if left on more or less permanently. Although I do turn amp and CD off if I am recording an FM broadcast on the Beeb. Quote
Daniel A Posted May 23, 2003 Report Posted May 23, 2003 I usually turn off my gear at night, allthough I tend to forget it at least once a week. My amp is a 1973 Harman/Kardon (solid state), and it's old enough to make me think it should be allowed to cool down once in a while. Besides, I'm always hesitant to leave - especially old - equipment running unattended. My turntable has been switched on (but not turning, though) for the last ten years, since the main power switch is broken. Quote
Jazzmoose Posted May 23, 2003 Report Posted May 23, 2003 My turntable has been switched on (but not turning, though) for the last ten years, since the main power switch is broken. Brilliant! That would stop my wife; I should have thought of that! Quote
DrJ Posted January 23, 2005 Report Posted January 23, 2005 (edited) I just found this thread - I leave everything on (AudioNote Meishu Phono tube amp and Audio Note tube DAC, Richard Gray's Power Company power source) all the time. The manuals (as well as my local dealer) recommend this...and I hear a huge improvement in sound with doing this. Turning the tube amp on and off really resulted in dramatic fluctuation in sound until the tube stuff got properly warmed up again which I found took a bunch of time (couple of hours minimum). Yes, it probably does result in faster tube wear but if you care enough to listen to tubes and put out for a quality listening system it would seem to me worth a few extra bucks in replacement tubes. I have a much lower end solid state home theater system centered around a Denon AVR3300 in the living room and turn that off every night. I have never heard a bit of difference in this system whether it is left on for a long time or turned off (although that could be related to its overall quality rather than there not being a difference with higher end solid state gear).

sidewinder Posted January 24, 2005 Report Posted January 24, 2005 Definitely worth leaving the power on 24/7 to those phono tubes so that they keep their thermal equilibrium, IMO. I do the same thing with the Linn and Naim kit. Transistorised and not tube kit but it seems to make a difference. When the power is switched off it takes a good half day or so to get back to the original, I find. PS - the only tube I have is an ex-Royal Navy Tetrode valve from about 1946 for use in gunnery control systems which was found gathering dust in an laboratory I used to work in many years ago. For exhibit only - that one is an absolute mutha !! Quote
porcy62 Posted January 24, 2005 Report Posted January 24, 2005 (edited) My contribution to the thread: Power amps (Solid State) and cd player are always on because you can't swich them off unless you plug them off, they are build to be in stand by all the time, a part when you listen to them! All other stuff, preamp (tube), phono preamp (SS), power conditoner and TT are switched off when I don't listen to them. The best sound comes after an hour of listening/warming. When I left home for a weekend or more I disconnet everything from the socket. I use to play some demagnetizing tracks (on cd and record) when I plug the system in. A part holy lightning and curse, I switch the system off because I don't want to contribute at the global warming for audiophile reasons. Edited January 24, 2005 by porcy62 Quote
Brandon Burke Posted January 24, 2005 Report Posted January 24, 2005 Hope I'm not bringing up something that's already been covered but..... What about non-audiophile stuff like old solid state recievers that very clearly fucntion as power amps as well? I'm running a Pioneer SX-780. It's nothing special but it is in beautiful shape and I really like it. Is this the kind of thing that would benefit from being left on? Quote
Free For All Posted January 24, 2005 Report Posted January 24, 2005 That's a beautiful amp. Worth seeing twice! Quote

wolff Posted January 25, 2005 Report Posted January 25, 2005 I've always left solid state gear on. I never leave tube gear on. For one, I've worked on some of the stuff myself, and would like to be around if something starts smoking. Some of the tubes I use are expensive(from the 50's and 60's) and will last my lifetime, but not if left on 24/7. Heat and power usage are more reasons I do not leave tube gear on. I had a pre-amp and mono blocks that had a total of 18 tubes a goin' and was very inefficient power wise. After 4 or 5 hours it was like a sauna. Quote
wolff Posted January 25, 2005 Report Posted January 25, 2005 Tube gear, stays on 24/7 (per dealer and manufacturer's recommendations, and my ears told me that when I tried turning it on and off it took forever to get back to peak sonics as the tubes etc gradually heated back up. Yeah, it'll probably shorten the tube life, but I'm already in deep, what's another few bucks? I'd be interested in knowing how many hours they say you'll get on the 300B. 10,000 hours? Quote
DrJ Posted January 25, 2005 Report Posted January 25, 2005 I deleted my post from yesterday...my EARLIER post had not appeared when I logged in to the board yesterday so I repeated it...now it's back...weird! Anyway wolff, I'll have to check on the expected tube life for the 300B...but my guess is that it's - well, a guess at best anyway. Quote
Brad Posted January 25, 2005 Report Posted January 25, 2005 So are you guys saying that if it's non-Tube, leave it on. I can't remember the name of my amp but my cd player is a Rotel. But it's ok to leave on? Quote
Guest ariceffron Posted January 25, 2005 Report Posted January 25, 2005 you guys make me want to vomit Quote
tooter Posted January 25, 2005 Report Posted January 25, 2005 Going back to the question of electric storms, I suffered once with a burnt out computer. Harddrive, CPU, almost everything, but insurance paid. However, I'm now supposed to be fully protected with a Surgemaster II power strip from which sprout umpteen power cables, antennaes and phone wires. Never been tested yet. Does anyone know how effective these things are? Can they be relied upon? I switch everything off when not in use for a few hours. Don't like the noise of the fan in the computer all the time and ever since I tried to download a huge file and left it unattended for a lengthy period - came back to find the harddrive kaput. So I'm superstitious about it now and "supervise" everything. Quote
Brandon Burke Posted January 25, 2005 Report Posted January 25, 2005 This is an awfuly strage thread. Every time I visit it it seems like a post or two are missing or an image is down. Then, when I come back the next day, they're back up and something else is gone. Quote

AllenLowe Posted January 26, 2005 Report Posted January 26, 2005 I think it's nuts to leave tube equipment on all the time - NOS tubes are slowly disappearing, current production tubes suck, and I hope you guys are all using the good old stuff - Quote
