well weekdays im on campus from 9am till 8pm. so my only listening gets done after 9pm until 12am. i dont think id want to leave them running the entire day just for the 3 hours of use at night. if reason or experience states otherwise, please let me know. thanks for all your responses.

is there a manual for new owners of tube amps anywhere nate? or a list of do's and dont's. wouldnt want to do something out of ignorance.

i wasnt tapping the tubes. i was tapping the case and i could hear the ringing sound. too scared to do anything to the tubes.

so i received this amp yesterday and i plugged it in last night in the following order. 1. put bendix 6080 tubes all the way in the back 2 sockets. 2. put the sylvania 6sn7 tube in the front. noticed that the metal base was slightly loose and could be moved a wee bit. 3. attached the necessary cables and then turned it on with the headphone plugged in. 4. listened to music. the gear loop is very simple and as follows. lenovo laptop (line out) - mini - rca cable - sp extreme - hd 650s. problem that only occurred last night if i even tap the amp lightly with my fingernail it sounds like it would if i were inside a tube and someone were tapping the glass. its kinda high pitched and something akin to the noise made when your ears are ringing in a game right after you get flashbanged (cant hear anything else but the loud ringing noise). this noise however is not loud, nor overbearing anything else. with no music it is very prominent though. is this just the hum associated with tube amps that other people were talking about? problem that occurred last night after 2 hours of listening to the amp (from the time i plugged it into the power) the left channel started making a LOT of noise. audible enough to drown out the entire music in the left channel. it sounded as if one were holding a plastic bag outside the window while driving. dont know how else to describe it but that i think is the most accurate description i can think of. sounds almost exactly like it. i turned off the amp and left it be for a few minutes. turned the amp on again and the same thing - lots of noise a few seconds after i turned on the amp. i turned off the amp and went to bed too scared to do anything else. just got up and tried another 6sn7 gt tube instead of the sylvania and no noise in the left channel so far. the amp did get exceptionally hot to the touch after 2 hours of use. i know that tube amps are supposed to run hot but i just wanted to make sure it couldnt have been the cause of the noise. listening to john lee hooker right now and everything sounds good. was it just a driver tube or could it be something with the amp. id rather not open it up and have a look inside unless i absolutely must. amp sounds marvelous otherwise. ps. i tried reading up on the topic last night but only found one thread regarding noise in the left channel in a darkvoice but the owner said it was intermittent. kept coming and going every few days or so. id rather have the amp be working in good condition considering it did cost a lot (to me).

this is just silliness.

happy bday sir. you were missed in tampa. hope you have a good one.

thanks for the help nate. i feel like an

if anyone finds a red mini-rca cable in their gear, please pm me and i will pay the shipping back to florida. hopefully it didnt get too far west with al it was one nate built for me, so id rather get it back instead of just get a ****ty one temporarily. it has neutrik jacks and does not have any kind of tubing on it. just red wire woven in braid.

yes, you certainly dont want to pass away...passing out...well thats a personal preference.

no internet...FOR 2 WEEKS!!! i would go crazy.

who is nenso? ps. happy birthday dude.

does switching out the fans void the warranty? this might have been answered elsewhere but has anyone asked david to just use better fans from the get go? im sure they have some "silent" fans in china or is it a cost issue to little dot? for the cost im starting to consider it along with my other tube options.

hope you have a great day. happy birthday man.

i think im going to sell the beta and get this. bet it sounds much better too.

just a little warning note...dont try that dvd at relatively high volumes for too long. it says so at the beginning of the dvd but being young and impulsive i forwarded past that portion and now ive had a massive headache for the past 3 days with a pretty bad earache to go with it. hope i didnt do any damage to my ears...couldnt do any more damage to my brain so not worried about that.

no offense man but thats sounds really really boring...cool but i dont think i could sit here and just listen to that for an hour. dreadhead, the volume was raised higher than normal.

well by hear i meant i could hear the diaphragm vibrating without creating any distortion. or as you said, i could feel it moving. but it was clean. no distortion. the 650s however were clipping at anything below 20hz.

ive been messing around with the following dvd http://www.rotarywoofer.com/demodvdwebpage/eminentdemodvd.html the gear is as follows. laptop (ibm t43) -> single ended beta 22 -> hd 650. all generic cables. i tried that bass test with the 650s and the lowest i could hear was the 30hz clip. at lower freq. i knew the driver was moving but it was just a bunch of distortion as if the driver wanted to do something but couldnt. i dont know if the source was prohibiting it from going even down to 24hz...it very well might be the case or is it freq. range listen for ideal conditions/theoretical under lab conditions? i ask because i just tried the crossroads iems i gave away to a friend and with those i could hear down to the 20hz clip. below that, there was a lot more distortion. did they seem to go lower because they are iems and closer to ear drum while the 650s movement of air is not severe enough to be noticed by my ears? chances are my ears arent the same as they were last year (i have noticed an increasing loss in hearing) but the fact that i could hear the freq. with the iems removes the ears as a probably culprit in the problem. oh and the iems were plugged in directly to my laptop (no amp), but the beta was used with the 650s. -cj edit: am i talking about getting the last few % out of the headphone with a much better amp + source with upgraded cables? i know the source needs to be replaced before i make any complaints against the sound but just wondering if theres an answer given the current rig.

Tractatus Logico-Philosophicus by Wittgenstein. read it 3 times already. every time i go through it i figure out new stuff or just things i read originally that dont make sense anymore upon further contemplation. excellent book if anyone wants to pick up some philosophy.

pico wins. because you can use it with pc's. duet = epic fail. because you can only use it with macs.

that is...any description of what has been done here would reduce the epicness so i will refrain from making any comments.

going to pick up the amp on sunday at naz's place.

well its not much like the usual meets posted in these boards but oz of let there be sound sent me an email inviting me to a local audiophile's home as he has graciously agreed to let people just walk in and audition his genesis speakers in some uber professionally treated room. also, the president of genesis speakers shall also be there at his house. oz included his cell phone number in case any of you would like to go or have any other questions. i plan on attending sometime after 2pm on sunday so if any fellow headfiers would like to go, pm me and we can meet up somewhere or just head over to the given address. sorry for the late post, but i just got to know about this event today. hope to see a few of you there. oz's email - "Howdy folks! Here's is my customer Naz's address which you can MapBlast: Nazurdeen Ali 16385 N.W. 16th Street Pembroke Pines For a telephone number please use my cell: (954) 465-5040 PLEASE shoot me an e-mail right back with your time preference between 10am and 6pm available on both days since we can only host 3 to 4 people at a time on any given listening session. You can each invite a couple of friends as well if they're into great music and you can schedule yourselves into the same time slot. Thank you, Oswaldo Martinez Let There Be Sound, Inc. P.S. Get back to me ASAP with your requested time slot please! Spots are filling in fast!!!" -cj

there actually is a temperature for each separate processor at which the soi (for old amd chippies, upto the fx series at least) wont do crap. they may have changed things with the new processors that are coming out but in the golden days of overclocking where you had to do everything manually in bios and not use some shitty app in windows to tune your rig, starting temps were just one of the many problems faced by overclockers. i had a 3 second delay on my phase unit with my fx 57, it had to boot at ~-37C and then cool down or it wont boot at all. in terms of condensation, thats a whole another monster to deal with. mass amounts of neoprene and dialectic grease become your best friends for the duration you own or operate a phase cooler/ a/c chiller. condensation proofing a motherboard takes as much time as building a chiller, many would say. that takes care of the condensation blowing up components part. as far as cracking due to extreme temperatures goes, phase units always have a giant copper head (direct die) that is applied directly to the processor instead of a air cooled heatsink. that usually takes away any and all heat and doesnt affect the rest of the board much. yes, the chipset temps are also very low but not low enough to cause any problems as long as your case is relatively stable. stay away from eocf if you can. i gave up my mod there a long time ago when i finally quick overclocking. its a worse time sink and a black hole for your wallet than headphones/amps/what have you. many might disagree or perhaps i just dont have the money to spend any more so it doesnt seem like a black hole for my money. having said that, any hobby where you push the limits of what is taken to be acceptable will come at a cost. what is to be gained by a world record bench mark...perhaps a bigger epenis but then again, what is to be gained by a 100k speaker rig? ill stop now before my argument gets misconstrued as something else. some nice people over at eocf though. learnt everything i know about hardware from those guys.

i very common practice amongst diyers over in the extremeoverclocking.com forums is to put a relay or some kinda time delay so that the processor can be put under some kinda load and then the phase cooling unit would start. if both were started at the same time, the processor would be too cold to even start functioning. (im talking about temps below -50C). in response to nate's question, couldnt one put a similar mechanism in place in series with the fan and see if the fan is getting power or not. if it is, then everyone gets cake, if not then it turns off the amp. im assuming its a lot easier saying it than actually doing it, but regardless of the amount of work, couldnt something like this be done? just as a safeguard. ps. jimp, thats a pretty looking amp. :drool:
