Little Dot I+ Tube Rolling - Page 99

post #1471 of 1962

With the help of Gibosi, I ordered a pair of 6BE6 valves and although I had some initial problems with one buzzing, I noticed a reasonable difference in openness and bass response. I'm sure it also depends on you headphones and mine (Q701) as kinda known as being a little "bass light" and although the 6BE6's didn't give me thundering bass, I definitely noticed a thicker sound without loosing clarity in that region. Everyone here will definitely put you in the right direction, I am new to this so cant offer much more.

I noticed a significant difference in going from the stock 6J1 to the M8100, but then, everyone has different ears and different gear. :)  As both the 6J1 and the M8100 are EF 95  tubes, it might be worth your while to change to another family of tubes, for example, the EF 91 or EF 92.

 

Or if you are willing to use non-traditional tubes, but still plug and play, 6GM6 and 6GY6 (set your LD for EF 92) are inexpensive and quite good. Also, 6BE6, 6BY6 and 6CS6 (set your LD for EF 95) are also inexpensive and quite good.

 

My current favorites among these are the 6BE6, 6BY6 and 6CS6. But again, everyone has different ears and different gear. As one of my colleagues notes, tubes are a lot like ice cream: The only way to learn which flavors are your favorites is to taste them all and then decide. :)

 

Happy tube rolling!

Yes, you may have to purchase some of these tubes from vendors in other countries. If you search for an item on eBay.co.uk, notice that on the left that you can choose location. Select "worldwide" and see if you can find some with low shipping costs. There are no European equivalents for the 6GM6 and 6GY6, but there are for the others.

 

6BE6 = EK90 and CV4012. (However, I found the Brimar CV4012 not worth the money). You can also search for this tube using the industrial version number, 5760.

6BY6 = EH900S, EH960, EH91H. And the industrial version numbers are 5915 and 6687

6CS6 = EH90. There are no other version numbers.

 

Good luck!

To be honest , id stick with the stock set up for a month or so , so you get to know the signature sound , this is what i did , the stock sound is fantastic anyway :)

It's a great little amp and I don't think you will regret your decision. And Mrlimbo's advice is wise. Live with the stock tubes and op amp for awhile. You might very well decide that it suits you very well.

 

Otherwise, the OPA2107 op amp is a very popular choice in this thread. For tubes, I suggest trying another 6AK5. The Mullard M8100 / CV4010 and Voshkod 6ZH1P-EV are at the top of most recommended lists. The Mullard can be a bit pricey, so the Voskhod might be a better first choice. And if one of these tubes does't suit you, there are many other choices.

 

Good luck!

Thank you very much...it is much appreciated.

just posted a very efficient way to clean tube pins in another thread, but maybe some of the tube rolling thread members are interested in my solution, so just crossposting the link here:

Wherever I've looked the Mullards are half the price of the Voshkods. Where can the Voshkods be bought cheap?

post #1482 of 1962

I bought two pair from this vendor:

 

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130436695928&ssPageName=ADME:L:OC:US:3160

 

$3 / pair, plus $12 shipping to the US. (I can't imagine that shipping to England would be more expensive?)  Incidentally, buying "matched" tubes would be a huge waste of money.

 

Edit: 6ZH1P-EV = 6J1P-EV. And what is important is the "EV" which signifies the highest quality Russian tubes.

Been a while since i have had the little dot but you can get them on ebay by searching EF95 and making sure that it searches other countries.  I bought 10 of em for 8 quid off a bloke in the ukraine.

That's a great price, especially for 1960's vintage. It is much more common to see 1980's vintage, which is not as desirable as these earlier tubes. You done good! :)
