Little Dot MKIII Tube Rolling - Page 182

post #2716 of 2867
Which tubes would be good to go with a pair of Beyerdynamic dt-880 600ohm? Would the stock be decent with them?
post #2717 of 2867

Hi

It's funny if you are from Toronto, Canada. I bought from a Canadian Ebay dealer from Toronto most of my EF95 type tubes for my DT880 600 ohm phones. Though my favourite tube are Mullard M8161 from EF92 family because they are the least warm and very detailed. After that my choice would be American EF95 type tubes as most neutral, best to me is GE JAN 5654W good detail and soundstage and $12 for a pair, and TUNG-SOL 5654 better soundstage but less detail, JAN RCA 5654W even more detail than GE but very small soundstage.

But If you want extreme bass your choice would be English military Mullard M8100/CV4010 also from EF95 family.

I don't remember the stock, I switched from them too soon, but they were decent I think but it depends on your luck as they don't get through much quality control I guess in China. Switching between tubes makes very audible difference, it's not like changing opamps or cables.

Hi sssboa,

 

The stock driver tubes I received that came with my Little Dot MkIII  were GE5654. These are pretty good, but as you can see, there are better choices. You have to try to find out what suits your taste the best.

It's funny what you write about Chinese quality control. My stock GE tubes looked the same, except for that one had black plate and one grey plate. I could not hear any difference, though. (One of the great myths about tubes is that black plate sounds better.)

 

BTW, I have only come across black, grey and silver plate. (The silver plate were RCA and did not sound good at all, but I don't think that the color of the plate contributes to the sound.)

I forgot that the stock tubes in MKIII and higher are not the Chinese valves as came in my MKII but they are GE JAN 5654W and they are very good as I wrote and they are my favourite EF95, so stock will sound fine. And colour of the plate does not make a difference. I had the type  same 5654 Tung-Sol black plate from 1956 and grey plate from I don't know 80s maybe and they sounded pretty much the same.

I just started considering tube rolling on my MKIII but I'm a bit puzzled by the different definitions on the models. I've decided on trying out the Voshkods and the M8100/CV4010, but I keep noticing on some items that "EF95" and "6AK5" is included in the titles. Could someone verify quick what this signifies? For example, I've seen Mullard EF95/CV850 which is a different tube.

Dear boyyo,

 

Different manufacturers gave different designations to tubes with the same or almost the same specifications. There could be more than a dozen different names for the 6AK5 tube. Tubes with the same designation usually sound different from different manufacturers. The best thing is to read through the blog and then you will get a good idea what to choose from.

How about LM Ericsson 403B?

Lycka till med tube rolling!

Tack!

So if I understand this correct: EF95 is Mullard's designation of the 6AK5? I'm guessing then that I would want to purchase this item: http://www.ebay.com/itm/M8100-CV4010-MULLARD-6AK5-EF95-E-MATCH-PAIR-VALVE-TUBE-81-27-/390368746675?pt=UK_Sound_Vision_Valves_Vacuum_Tubes&hash=item5ae3ca5cb3 for the M8100/CV4010 that has been recommended here on head-fi?

 

I've no idea about the Ericsson 403B, first time I hear about them. I will look them up and see what I find. I mostly want something bass-heavy with good treble and warmth, thus my choice for the Voshkod 6ZH1P-EV and CV4010 Mullard.

 

Also, is there any point in changing the stock power tubes? I've read that 6H30pi is a popular choice. But I've also heard that the 6H30pi doesn't match very well with the MKIII and works best with MKIV.

Hi boyyo,

 

The answers to ALL your questions are on this blog. Take the time, and read through the entries from the beginning with a notebook in hand. After you read it, you will become an expert on tubes for the MKIII. It takes time, but it is worth it.

 

Head-Fi has another tube blog for the Little Dot, and the first entry there is very helpful, as well as all the other entries. Here is the link:

Dear boyyo,

I can second mordy's post, incuding the link to the other thread. I would suggest to include these tubes in your tube rolling, you will not regret it wink_face.gif:

post #2725 of 2867

I am mainly blaming Penchum, because of his fantastic review, today I have ordered the little dot mkiii, a pair of sennheiser hd650, Voshkod 6ZH1P-EV Matched Pair, Sylvania JHS 6AK5 Matched Pair, and I am looking at the mullard m8100. I cant wait to start the burn! z

 

just connected everything....wow,  and this sound is going to get better!!

 

just slipped in the voshkods. straight out of the box with no burn the tubes are really special. the music has so much more life. wow

i also have the mullards and the sylvania but they will have to wait!

Congrats zedmeco, you will surely enjoy this setup. If you want to treat yourself for Xmas (again ;) ), have a look at a pair of 6H30 tubes (I got the Sovtek 6H30-EV). This is another step up. It was the first time it made me realise how good or bad my driver tubes are in terms of spatial focus. Some were more blurred than others.

After recent auditioning, I picked the Voskhod 6ZH1P-EV and the Mullard M8100 KB/D (small Mullard logo, I linked above) as my favourites, so far. I am not using the CV4010 "no Mullard logo" nor even my otherwise loved Sylvania JAN 5654Ws any more.

Hi, how do you change the jumper setting to EF 91? At the moment I have all switches left and right positioned on the left hand side. (viewing the amp upside down volume control at the front left)

 

Any help much appreciated, as I donot want to damage my amp with the wrong jumper settings.

 

Many thanks.

 

Mike

D**n you, d**n you all!  wink_face.gif


I've been reading easily over 300 + pages on this forum and it has made a very big HOLE in my wallet...
I became interested in a headphone amplifier for 3 months ago because I never got to listen to my music on my home theater system for the last 3 years. Because my girlfriend she suffers from Tinitus. (X-girlfriend I want to add ...)

I became aware of the Little Dot MKIII and had almost made ​​up my mind on the MK III version, when I read more & more on this forum so it became that I decided to update & go directly to the Little dot MKIV SE model instead, because there were more opportunities with tube rolling and better components.

As I was going to start in a few months to keep the cash flow down ... Do you think I could stick to it!?! A wery big NOOOOOO!!!!rolleyes.gif


Now it has gone so far that I have stuck in tubswopping- swamp and has for the past two weeks has order a Little Dot MKIV SE + approx. 50 tubes ...

I got my Little Dot today & have been recived 16 tubes already! :-D

My collection of tubes looks / or will look like this in the near future:

 


2st. Electro Harmonix 6H30PI Gold-Pin -12             M. PAIR
2st. 6N6P Gold Grid Double Triode -78                    M. PAIR
10st. 6N6P Gold Grid Double Triode -80
2st. 6N6P Gold Grid Double Triode -63
2st. SOVTEK 6H30PI-EB ARC Conrad Johnson -11  M.PAIR

2st. 6J1P-EV Gold-Platinum grid Gold Pins -77       M. PAIR
4st. 6J1P-EV / 6ZH1P-EV Gold Grid -80                 M. Quad
22st. 6J1P-EV Gold-Platinum grid -71 -75
2st. Voshkod 6ZH1P-EV -80?
4st. Mullard M8161 CV4015 -80
2st. M8100 CV4010 -83                                        M. PAIR
4st. GE JAN5654W                                              M. PAIR

I hope you understand that I mean that I am extremely grateful for all the posts that you all have contributed with, both + and -. That has been much appreciated by me! k701smile.gif

 

Now it will probably take a while before I can help with some impression of what I, experience with different combinations of tubes. So I hope you have the time and inclination to wait a few months before I can help with some impressions of what I would recomend others to try.
What I listen with are a new pair of AKG K701.
I have something like that some people called 'job' to take care of alsow...

(If it is reasonably difficult to understand me, so I blame it on Google Translate!
wink.gif


Have not used my English so much the last 20 years since I graduated...

 

Now I'm going to disappear into my cinema room for the next few hours in order to plug in my little dot & just enjoy life ...L3000.gif


Best regards to you all from me, S60R.
