    uninterruptible power supply

    Post by MontanaWay on Sat Apr 26, 2014 2:31 pm

    has anyone ever used or considered using a UPS for the amp, not so much for backup when power fails, but more for a 'almost guaranteed' clean stable mains supply, irrespective of mains fluctuations.

    I use a Furman SPR 20i which clamps the voltage on the high side at 121 VAC or wherever you want to set it. We get some pretty wild line voltage fluctuations here; six deep mines in operation, each with a 2,000 horsepower shaft, plus compressors and mills that go on and off line. I've measured as low as 114 VAC and as high as 128. The Furman ain't cheap, about 2 large, but you get protection up to 140 volts input from the wall, after which it commits suicide. I don't worry about low voltage, but overvolt is murder on our stuff.

    The other essential component in your power connection is a MANUAL RESET ground-fault interrupter (GFI). It protects you from those 30-second power-off-on blips that can fry any Dynaco or VTA power supply. They're about $30 on Amazon or probably Radium Shack. With a manual reset, when the juice goes off, it doesn't come back on until you wait about a beer's length, then reach around behind the hutch and reset it. Keeps all them gadgets and capacitors and things out of harm's way. GFI's also come with auto-reset, which defeats the whole purpose of having one to protect your toobs.
    Here's the one I have:

    What you are talking about is a power conditioner, not just a UPS. If you decide to go that route be sure you know what you are getting.

    Agreed. If you were going to go minimalist, go with the $30 manual GFI. Power spikes are intermittent and you're not likely to cook anything; it's that 30-second on-off from the line that fries our stuff. Filaments and plates can take a 10 percent overvolt or undervolt if it ain't too long, and you'll know because your house-lights will tell you. It's that quick bang-on after an outage that's bad. Not so much the spike as the timing.

    OK, good advise. Sure as heck is cheaper than a UPS too!, thanks guys!

    Yup ... the ones that are in your house panel are worthless when it comes to blips and the damage they can do to tube equipment. The GFCI part isn't really an issue - it's the manual reset that's important. That allows you to let the amp "rest" and discharge properly before you hit it with another slug of juice. Couple minutes before resetting it does the trick.

    I went with this one ... down to $18 now at Amazon ... came in handy just a couple weeks ago when Ma Nature had a hissy fit in my neck 'o da woods ...

    I read down through the reviews and it appears that it is manual reset. Somebody was bitching about the fish in his aquarium getting cold when he wasn't home 'cuz he had to manually reset it. Get one rated for at least 15 amps. Ideally, you should go down to your electrical panel and dedicate one 20-amp breaker to the outlet you're using to power up your sound system with. That's about as good as a "power conditioner" can do for you, and for 2 kilobucks less.

    I should add that the circuit be dedicated to only your sound system outlet, so if the wife fires up her hair-dryer or blender you won't get any spurious AC noise (as if you could hear it over a hair-dryer or blender). That way at least you don't get internal voltage swings.
    I guess I was a bit silly to buy the Furman, but it's fun to see how much juice you're pulling out of the wall when the Big Tubes are working hard. With the GZ-33s and Vandersteen subwoofs with the M-125s and Roy's two pre-amps and a fairly serious need for R&R I can pull 9 amps. That's um, times 120 VAC, about 1,000 watts. It's fun to hit that target, although the neighbours get uppity.
    Haven't tried sKIzo's lamp shades on the rectifiers yet, but temptation draweth nigh.

    If you want to see what your power draw is just get one of those kill-o-watt plug in meter things.

    That's a long haul to Oz, even from the left coast.
    Am going to central Africa in two weeks. Maybe this board needs cooling down.

    Just ordered one what ... a wife?
    (ba dump dump)

    For those who wonder about the manual reset bit on the one I posted ...

    To prevent unmonitored equipment startup, manual reset is required after GFCI trip and power outage.  Available in yellow with button boots or white.  Provides compliance with National Electric Code (NEC 2008) Article 590.6 for "Temporary Installations".

    Cool. Don't forget to turn you toobs off when you leave for Oz. The power bill will astound.

    Stick your tongue in the nearest socket ... that should test the system for ya ...

    They DO have a test button them ... if that trips the doohickey, you should be golden.
