Pretty clueless..

just want to buy a toob amp and have it make beautiful music for me :3
Both tubes should be replaced from the stock. A good starter set is a RCA 6sn7 and RCA 6as7. Should be able to get both tubes for around $40 on eBay. "Best" tubes will vary depending on what you want

OTL amps typically don't work well with low imp/ohm HPs. HE-4 is rated at 38 so I don't know if they'll play well. I think you'll lose out on the bass end unless you do the mod.

I have a 336 w/o the mods and I don't need to cap fix. It's only required if you hear a buzzing. Get it first and see if it's required.

I agree on both fronts. I replace with NOS RCA's. Both tubes cost me under 100$, and the difference was night and day.

 

I found the 336 to be winy, and gritty at first, but the tubes surely opened things up warmly.

HE-4 + 336 = a money setup IMO. Make sure to pickup a sold DAC, and interconnects I use Yacco's. For 50$ they can't be beat. http://www.audioreview.com/cat/cables/interconnect-cables/yacco/whirly-wisp/prd_446064_5827crx.aspx

Just received DV336se with stock tubes. Left channel has a low buzzing. Is this matter of burning in or I have some sort of problem? I know that stock tubes is probably not the best option however, I'm worrying that there is a problem with the unit. It actually sounds pretty good so far but that hum drives me crazy. Any advise?

post #1490 of 1497

Not exactly tube rolling, but i don't see to many other popular threads about my amp specifically. My 336SE has a hum that is barely detectable at low volume, and fairly noticeable when no sound is playing, gets louder as i turn up the volume, still there with nothing but a power cord in it, have a good cord on the way btw. I have kept the stock tubes, but plan to upgrade. so do you think its ground loop hum? and could i fix it with a power conditioner or something along those lines?

 

PS. when you set this up as a preamp with some Cary CAD 805 mono blocks it just begs you to sit and listen for hours, so gentile and easy to listen, yet punchy bass and clear mids and highs, really has a certain magic to it. It gave my audio valve preamp a run for its four thousand dollar price tag. So, am i going to "upgrade" the tubes and go 0_0?(mainly use this with grado 325IS but just had to test it with carys and MY GOD this has to be the best preamp/headphone amp i have heard anywhere under the 1000 dollar range. To nitpick, the audio valve has slightly wider sound stage, and less bass, but i cant complain, i got it for about 110 dollars on mass drop after a late shipment reimbursement. (recommended general upgrade tubes that are not to expensive)?

 

Thanks for any good help?

 

WELL, that was longer winded than i had intended.....

 

Again sorry for going off topic.

 

*moved to a different electrical circuit did the same thing, and i do have a lot of dimmers in my house, pulled out the manual shut off switch on every one, makes no difference, tried a Pangea AC-9 power cable and no difference. I heard of a mod to stop other tubes from humming, where you solder in 2 220 uf caps at ~3 and 9 o'clock on the input tube socket and then to to a common rail? might this help?*

I would try moving it to another room/electric circuit and see if that makes a difference. Sometimes a ceiling fan or even a rheostat can create noise.

I would unplug and replug the tubes.      Also I have read burning in the tubes may cure it.    In the mean time get a set of tubes off of fleabay.

I have a 336i. Not too sure if there are any significant changes inside the amp (compared to the SE version), but with mine, some tubes will hum, others will not. Sometimes the hum will fade away as the hours pass. Sometimes not. So, in mine, the tubes are the culprit of any hum and a quick swap to another tube can make it go away... or get worse. (Usually the 6sn7) This was obviously more of a concern while I was tube rolling. I have since settled on a nice Bendix 6080 and Tung Sol tall bottle 6sn7 and havn't had any issues for a seriously long time.

However, like the previous post said, the electrical conditions in the room can have some say in the amp humming as well.

Are there a lot of tubes that go by different name than what mine is labeled on the front, (6sn7/6as7) or should i just stick to some RCA,s or something.

post #1494 of 1497
The back one (6as7) can also take 5998, 2399, 6080 and 7236s as direct drop ins.

thanks for the info

Should I get a warm syrupy sound while not losing alot of detail and sound stage if I went with a 

RCA 6AS7G gray plate

and 

RCA 6SN7GT black plate greyed out ?

 

I am using DT990/250 which i would love to warm up and I later on intend on getting HD650 with a Brimar 6080.

 

Sound like a plan?

That is certainly worth trying.
