Little Dot I+ Tube Rolling
Jun 12, 2011 at 8:41 AM Post #1,141 of 3,154
NEVERMIND. i got it. trying to get the OPAMP out now. seems tricky. i don't want to break anything.
 
EDIT: UGH how do you get a grip on this little thing??
 
EDIT 2: Wait what do you guys mean 'careful not to bend the legs'? It won't go in unless the legs are pushed in a bit?
 
EDIT 3: Ok, i got it! This sounds great! definitely a thicker/meatier sound. richer. excited to listen with my new turntable when my nad pp2 and new cartridge comes in! :) Listening with RS-1s, flat pads, and Mullard EF91 through a uDAC.

Glad that you changed the op-amp. Many chips I had to reform the legs by bending one side of the chip a bit with a straight edge to make sure that the legs are at 90 degrees. What I meet by not bending the legs was not to crush the legs underneath the chip or sticking out while pushing the chip or op-amp into the socket.
 
Gee, more poeple are getting turntables!

I figured I may as well post here first that I'm going to be putting my barely-month-old LD up for sale here, along with extra 408A tubes and a few different opamps. Probably this evening, so check out the for sale forum later on.

I got my OPA2107 in (also had to bend the legs in a little bit, so don't worry cruizin caleb) and it does sound a little deeper, I can definitely get some more bass going, now I just need to get some tubes to role, was thinking about M8100's and WE 408a's, anyone care to comment?

Both those tubes are good choices, but in my experience the WE 408a is similar to the M8100's only much better. I think you may hear more of a difference trying a Mullard EF91/92 ; they offer a more warm cosy sound compared to the 408a's. I really like the 408a's though and I now find it hard to listen to my other tubes. They offer such clarity and bigger soundstage, abeit' at a little expense of warmth.. but you can't have everything! just almost.

How do the WE408a's compare with the Sylvania gold brand 408a's?



Havent heard them. But i've read that they are very tubey and engaging, although apparently with a slighly smaller soundstage. If I ever see any on Ebay I'll be snapping em up to give them a try

I'll be receiving my Little Dot 1+ within a week or two. It's paired with the WE480As and the LT1364 LM4562 opamp. I'm going to be using these with 32 ohm DT880s.
If I don't like the sound, I'll go buy an opa2107 and see how that works out. I'll post my thoughts here soon.
 
EDIT: Due to some complaints about the high DC offset of the LT1364, I will refrain from using that opamp and will use the LM4562 in its stead (also came with the amp). Better safe than sorry.

Congratulations! Looking forward to hearing what you think of your new amp!

Anyone else have trouble with the Ef95 family of tubes? I recently received some Amperex 6ak5w tubes. And there is a buzzing going on in my right ear. And switching around the tubes does nothing. I also had the exact same issue with some Ef95 russian groove tubes. 6zh1p russian do the same buzzing in the right ear. It has to be the unit right?

just a long shot but you did change the jumber settings if needed right? I found that changing to ef95's from the ef92 settings, that the amp acted strange and If I touched the amp it made a noise. This did calm down after a while though. I think it would be strange for two different lots of tubes to have buzzing in the right ear. I would make double sure that you have the jumbers in the right place.

[size=10pt]I'd try a few simple steps... [/size]
  1. [size=10pt]clean the tube sockets with some deoxit[/size]
  2. [size=10pt]Move the amp around to be sure you're getting no RF, some tubes are more susceptible to it[/size]
