Thank you for those suggestions.
 
By the way I have JAN 5654's in my Little Dot 1+ and they pack a punch.

I use the same tubes and really like them. Just lost one though so going to have to grab another set.

Give those Telefunken 5654's a try (if you haven't already)  They are also great in the Little Dot 1+

I've just bought a used Little Dot mk3 off ebay and I am unsure whether I have the jumpers that allow switching between EF92 and EF95 tubes. There were no separate jumpers in the package and the person I bought the LD from only used it once and didn't remember there being any separate jumpers. The drive tubes in the LD are General Electric GE5654, which I think are EF95 tubes, which would be compatible with the instruction booklet saying the factory default is for no jumpers (for EF95 tubes). And yet when I look through the viewing holes to the jumper switches I can see a black jumper across two of the three pins in each bank. I hasten to add that I have next to zero technical knowledge with switches and things electrical generally, so don't know what to make of this. Grateful for any advice. Thanks.

i might ad that on my MK3 jumpers are always on one side EF95 or the other EF92 Theres 3 pins so depending on tube type its either the 2 pins to the left or the 2 pins to the right that you use

Ah, so I do have them. The LD is working well with the GE tubes, so if I want to use EF92 tubes I just move the jumpers across to cover the middle and currently exposed pins?

Yes it would be the  first 2 pins on the left in my picture

Great, thanks.

I must say that this is the first I have used the LD since getting it a couple of weeks ago, and I accept that the tubes are no where near run-in yet, but I am already bowled over by how good it sounds. I'm playing 16/44 alac files from iTunes on my iMac, running through a Jitterbug and Chord Mojo. I tried first with AQ NightHawk headphones, which was good but no where near as good as with the Focal Utopias (DHC Prion cable). This will be my study setup but I will at some point also tryout with the Chord DAVE from my main system, and then on to some tube rolling.

My best setup for the MK3 was using adapters with 6SN7 as power tubes and adapters with C3G used as drivers i used mainly Senns HD800  with the MK3 well regarded drivers and also cheap are the 6HM5 tall bottle tubes at around $5.00 each and as power tubes the Russian 6N6PIR tubes which are about $30.00/ pair  here'a power tube review from this thread maybe you havent seen it  page 201post #3007 in the littledot tube rolling guide thread here  http://www.head-fi.org/t/563884/little-dot-tube-amps-vacuum-tube-rolling-guide/3000

As always thanks for all the info you provide to all members.  What converter adapters do I need for the 6SN7 tubes for the Little Dot III in photo below?  I can't tell.

  
Thanks,
Anthony

One more thing if i recall not sure the adapters  are going to fit in the rings they are to big. in the picture it seemed to work as some adapters had longer pins .Personnally i removed all the rings on the Littledot

 

[dobigstuff]

Thanks for the help!!

HI Dobigstuff,
 
If the adapters are too wide to fit inside the decorative rings in the MKIII, you could buy inexpensive 9pin socket extenders. Won't win the beauty contest, but works.

It is possible to remove the brass rings, but may entail some difficulty.
