But make sure you handle the C3g's with utmost care!
They are extremely fragile mechanically (than most other tubes)!

Hi guys,

Now, I got really confused.
I was searching through ebay, and I did find the 6AK5, but it says, 6AK5 EF95, so, if this is a EF95, then I don't need any adapter, as its just plug in, my Little Dot MK II is compatible with the E95, the 6J1P-EV I'm using now are EF95.
So, is ebay wrong, is it me, or is both of us. Or none. lol


Cheers,

The Radio Museum site can be very helpful in determining equivalents:
http://www.radiomuseum.org/tubes/tube_6ak5.html

~~~~~~~~
Identical to 6AK5 = EF95 = 6Ж1П = 6069 = 6F32V = 6F32 = 403A = 731A = PM05

Similar Tubes

Other shape (e.g. bulb type):
CK604A

Normally replaceable-slightly different:
6AK5A-TS ; 6J1

Other class quality (otherwise equal):
5654 ; 6AK5W ; 6J1-Q ; CV850 ; GL-5654 ; M8100
~~~~~~~~~

I am not sure what tube you are referring to, but you can run any of the above tubes using the EF95 setting, without adapters.

If you are talking about the C3g, compared to the EF95/6AK5, it has a different base and different connections and definitely requires an adapter. However, with an adapter it is pin compatible with the EF95.

Thank you gibosi !

I think I was confused with the references. ( noob alert ! ) lol
Ill dig a lot more, and take a look at the link you just posted.

Should Russian 6h8c tubes work as power tubes in IV SE? I have pair of those with adapters, but can't get anything out of them.

I'm using the 6H8C, 6N8S and other 6SN7 on adapters as power tubles on my Mk4SE.
They work well when coupled with my HiZ cans. Not recommended for phones with <100 ohm impedance, you will hear distortions at peaks.

 

[Topodomain]

Hmm, that's odd. Maybe my tubes are busted or adapters are not what they should be. I'll have to find out pinouts and at least measure adapter.

5.1 Can’t Decide Which Tube to Buy?

To Little Dot’s credit, their Mk-series amps have an impressive number of tube rolling options and there are more than a few very informative threads dedicated to this topic. I would recommend anybody interested in upgrading their stock tubes to take advantage of our collective knowledge and take a look at those threads. Occasionally I have received PMs from new members who are overwhelmed by the sheer number of tube rolling options, and asked for my recommendations so they can stop reading forums and get back to listening to their music. So here’s my short list: I would recommend the Voshkod 6ZH1P-EV as the best place to start as it is a clear upgrade from the stock tubes, followed by the Mullard M8083 for its impressive treble clarity and top-octave ‘air’ (provided you have matched power tubes). The RCA 5654 (black plate) is also a wonderful option for its solid all-around performance, great bass response and availability.

5.2 Tube Sellers

I’m very picky about whom I purchase my tubes from, particularly about how they match and test their tubes as well as warranty periods. The following is a quick list of tube sellers that I have personally dealt with and have been happy with. There are certainly many more just a Google search away.

Yen Audio
TubeDepot
VacuumTubes.net

Recently purchased a Little Dot MKIII through Massdrop and have been experimenting with various tubes--from suggestions from this thread. A big thank you for all the contributors--I have no clue about this stuff and am happy to get any advice.
I have a set of Fostex TH 900 with the Silver Dragon cord from Moon Audio--hoping to tamp down the excessive high end.
Really want to know if there is a good tube to match to these headphones that will tame the high end--
I really love the bass and sound of these headphones but---damn, the high end can get really piercing and frankly unlistenable with certain tracks.
If anyone has any knowledge and experience with this I would be grateful for any advice--
thanks!

Try to use EQ instead of tube rolling,Tube rolling can get expensive(at least for me).

Good advice--
I use EQ when I am playing tracks on my AK 120 II--plugged into the Little Dot.
I recently bought a stand alone Tascam cd player and have it plugged in directly to the Little Dot.
I just ordered a Behringer FBQ1502HD EQ--that should do the trick.

LDMKIV tube rolling question from a newbie.

Bought my first tube to roll with: a pair of Mesa Boogie EL84/6BQ5s, recommended by a local dealer. They aren't working right: there's hardly any sound, just horrible static.

They are seated correctly, and I have de-oxidised the pins. They do not appear to be damaged or dead (silver top, no purple glow etc), and I bought them from a reputable dealer. Stock tubes working fine, with good sound, so it's not the amp itself. Before I send them back: it occurs to me that I may need to change the jumper switches. But I don't know what these look like, and Google is no help. Neither unfortunately is the LD manual/reference guide.

Do I need to change the jumper switches? If so, where are they? And please don't say 'next to the capacitors' - assume I'm an idiot please! Muchas gracias

 

[gibosi]

The 6BQ5 will not work in the LD4. See below for compatible tubes.
