Little Dot Tube Amps: Vacuum Tube Rolling Guide
Mar 28, 2017 at 7:39 PM Post #10,906 of 13,430
Thanks for the recommendations on tubes and section of this forum to get info. I will need to do a lot of reading to familiarize myself with tube rolling. Sounds like a fun hobby. What tubes would you recommend for the LD mkII and a pair of sennheiser hd800?

Finally have all the pieces in play.  See Below:  (Still need to get some NOS 6SN7's)

  What power tubes do you use for c3g? (for MK2/MK3)


​Everything I've used with the c3g's has sounded good, 6n6p/ir , and my 6sn7's, EH, Philips JAN6sn7wgta and PSAVENE UK-6SN7. At the mo I've got hold of some Foton 1965 6n6p and they sound great with them too, my experience so far is that they pair well with most tubes.

Ok, then maybe in the summer I'll order some of these:

At the moment I try to use what I have, because I already have a "stockpile" of tubes and I still haven't tried the 6HM5.
And again comes in my mind the question: C3G or MK4 or Feliks Audio Elise? And for Feliks I cannot use the "stockpile" so another tube quest is starting and so on. I feel like a hamster trying to keep busy :D

  Question: I was looking through my collection of tubes and found a pair of Mullard E88CC/01 NOS. Will these work in a Little Dot MkIII?
Also, how about a pair of Amperex 6DJ8 Bugle Boys?

Back in the day I made a couple of 6dj8 adapters and as far as i know there is no ready made adapter adapters on Ebay for use with this tube here's are  the ones i made and the schematic if you want to make one or if your interested in mine send me a pm.if you want to know more about this use the SEARCH FUNCTION atop the page

​I think a lot can sympathise with that !. :)

Hi guys.
 
It warms my heart that the C3g is still well regarded after all this time, and since I defected to kick start the Feliks-Audio Elise (in the hope I could adapt these wonderful tubes to also work in its 6SN7/6AS7G configuration...and which it does very well indeed lol!..even though I've since betrayed my beloved C3g'S' by adapting other tubes in its place

...).
 
And of course therefore, OctavianH, I have to recommend you go for the Elise...it surpassed by a good margin even my MKIV SE, complete with Siemens C3g 'S'/GEC CV2523 (6AS7G) combo!!
But good luck with whatever you finally choose...

I won't go so far as to endorse any one amp, but I do not believe that the MK4 is enough of an upgrade over the MK2 to be worth the money. On the other hand, if and when you decide that an upgrade is in your future, a 6AS7 / 6SN7 amp, such as the Elise, will blow the MK4 out of the water.
 
But of course, an improvement of this magnitude comes with price to match. These amps are more expensive and the tubes are more expensive. So if you can find a way to stay happy with the MK2, your wallet will thank you. :)

This is exactly my opinion guys about the MK series.MK2-3-4 are almost the same design but with better components and better tubes. I guess the guys at Little dot designed MK2, then saw it was getting quite hot so they changed the chasis and improved some of the design and sold it as MK3. And then they continued to add more expensive capacitors and jacks and stuff and created the MK4. But an upgraded MK2 like mine has to be very near of his bigger brothers and the price difference for the upgrade does not provide the same amount of performance increase.
Now, since I own the MK2 for less than a year I plan to keep it, at least now.
 
But can anyone describe me more the difference of the sound of Elise?
 
How is the sound compared to MK series and what is much better there?

I am considering replacing the Mullard CV4010 driver valves in my LD Mk III with C3Gs. Do you think they will be a good match with the NOS Sylvania 5687 (on adapters) which I am currently using as output valves? Are they a drop-in replacement (with the correct adapters), or do I need to adjust the jumpers?

Also, is there a reversible, non-destructive way of removing the brass rings? I don't really want to be stacking adapters on top of socket savers!

The amp is primarily used with 600 Ohm DT880s and modified 250 Ohm DT770s (occasionally 25 Ohm DT48E).

The rings have to be unscrewed from the inside of the chasis so you have to remove the board inside to get to those screws .i used a dremel to cut them way way easier. and if you want rings you can always get them on Ebay maybe even to fit the bigger tubes you will be using.
