jt1stcav Posted October 27, 2005 Share Posted October 27, 2005 Yeah, Steve...that's true...LOL! If I had the spare coin, I'd probably have upgraded my amp by now too. Quote Link to comment Share on other sites More sharing options...

crazytubepower Posted October 28, 2005 Author Share Posted October 28, 2005 The only thing that now bugs me is I cannot leave my amp on 24/7, well at least I don't think its good for the life of the tubes. I could be wrong, as I have been before. Quote Link to comment Share on other sites More sharing options...

I could be wrong, as I have been before. Just turn them on when your day begins and off at night before you dose off its better to do the on/off cycle especially with a SS rectified units once a day. If you going to be gone at school all day don't turn them on until you get home. Another great safety trick for malfunctioning disaster is to buy numerous values of fuses for the amp below the factory rating keep lowering the value until you experience a fuse blow while listening to music (not when you turn the amp on) then use the fuse value just above it. Most manufacturers use fuses rated higher then necessary to insure they don't blow I myself prefer to use just enough fuse for the amp to run under normal conditions. I'd rather replace a fuse then a tube, transformer or some other component. Craig Quote Link to comment Share on other sites More sharing options...
maxg Posted October 28, 2005 Share Posted October 28, 2005 "Berning ZH270 is tube 70 watts per channel, and weighs 12 lbs" Wow!!! My tube amp is also 70 wpc. It weighs slightly more than that. In fact the separate power supply weighs 14 kilograms (2.2 lbs to the kilo - er....31 lbs give or take). At 12 lbs you are in the digital amp sizing category IME.

Cal Blacksmith Posted October 28, 2005 Share Posted October 28, 2005 Congrats on the new amp. It sure is a pretty one, a real looker. A resized photo would have been nice for us dial up types but it loaded eventually. Give it some time for your ears and the amp to settle in together. There is no reason to leave it on 24/7 As NOS said, just turn it on when you want to listen to it and turn it off at the end of the day. I would keep the original tubes and try them later just to see if there is much of a difference. It never hurts to have a back up set to use while shopping for replacements.

dbflash Posted October 28, 2005 Share Posted October 28, 2005 Nice looking amp. Also remember that it takes awhile for it to warm up. I will turn my amps on Saturday morning and they really start sounding good by the afternoon. If I know I am going to be listening to music Friday night I power my system up Thursday night when I get home from work. This also lets me listen Friday morning to music while I am drinking coffee.

Cal Blacksmith Posted October 28, 2005 Share Posted October 28, 2005 Err..... Danny, it should be just about as warm as it is going to get in about 1/2 hour, no reason to go overnight[] Quote Link to comment Share on other sites More sharing options...
NOSValves Posted October 28, 2005 Share Posted October 28, 2005 Danny, In your situation my advise above is a good idea to protect your amps/system while your gone at work. Try it out I bet the amps can do fine with a 2 amp slow blow. The preamp may get away with a 3/4 amp fast blow. Craig Quote Link to comment Share on other sites More sharing options...
dbflash Posted October 28, 2005 Share Posted October 28, 2005 Mr Blacksmith I usually agree with you, but this time I have to disagree. On MY system it takes a couple hours before my system "zones" in. It just seems to my ears that the Hi's get crisper and more open sounding. the Mids warm up and the bass drops down to where it suppose to be. If I just power it up and put a Cd in, there are no Hi's to write home about. It's just Bass all over the room. Don't get me wrong it still sounds good after a CD or two, but it just sounds better after a couple hours of warm up. Danny Quote Link to comment Share on other sites More sharing options...
Cal Blacksmith Posted October 28, 2005 Share Posted October 28, 2005 Hey, it's your system and your ears...... Ya gotta do what sounds best! No offense intended and I hope none was received. My apology to you if I was over the line. Quote Link to comment Share on other sites More sharing options...
dbflash Posted October 28, 2005 Share Posted October 28, 2005 From you never. You have never been less than a class act. Like I said I usually agree with most of what you post, but if I didn't I know I can reply and not worry about you and I shutting the thread down.

AnalOg Posted October 28, 2005 Share Posted October 28, 2005 I agree, my system starts to sound good after about half hour, an hour later balanced and open is the best to discribe what I exhibit. Maybe its a equipment issue or maybe the protons flow better after an hour....NOT! Tom Quote Link to comment Share on other sites More sharing options...
D-MAN Posted October 28, 2005 Share Posted October 28, 2005 Guys - is it REALLY warm-up time - or just the time of day (or night) that you listen seriously? The power grid quiets down later at night when people go to bed, etc. I mention this because the tubes, transformers, etc., are all up to nominal operating temperature after just a couple of minutes. It doesn't make sense to me that the gear needs to warm-up that long to reach its optimum properties. Just something to think about... BTW, that is a beautiful looking piece of gear.

audiobliss69 Posted October 28, 2005 Share Posted October 28, 2005 NOSValves - Could you explain to me your reasoning for changing the fuses like that? What you said caught my attention, but I can't say as I understand what you're talking about. audiobliss Quote Link to comment Share on other sites More sharing options...

crazytubepower Posted October 28, 2005 Author Share Posted October 28, 2005 Basically, underrating the fuse, means it will blow easier, this saving the equipment is more likly. I would rather replace a blown fuse, than replace a dead tube. So yes craig's advice is very smart Quote Link to comment Share on other sites More sharing options...

NOSValves Posted October 28, 2005 Share Posted October 28, 2005 audioblis, The people above answered it perfectly. The safest fuse size is the lowest the amp will run with! Like the young guy said he would rather replace and fuse then a tube. Craig Quote Link to comment Share on other sites More sharing options...
