It came with a bad 6N6 tube

The sound of the cheaper tubes provided with the unit are just fine - although I will roll the tubes at some later date.

The tubes need a good 70-100 hours of use to 'burn in' so hopefully it will only get better from here.

Only complaint about packaging is that they used packing tape to secure the tubes which left sticky residue on them.

I am still looking for good tubes for this and have already picked up a cheap, $15, matched pair of the bigger tubes and they sound better than the ones it came with and they were the cheapest ones that I could find that people were suggesting

I found a wonderful tube rolling guide on “Head-Fi” that pretty much runs the gamut of options for the Little Dot MK2 and 3.

I believe that the LD Mk2 should already sell with good sounding tubes not these chinese crap drivers

The Russian and British tubes are not even that expensive on eBay and you will be glad you did

Now I also use the Little Dot as a tube buffer as well and I am addicted to the sound and I am planning to buy a tube integrated for vinyl playback

Certain tubes work great for certain speakers

Certain tubes work great for certain speakers

but they do put out a tad less power than the super tubes

I chose to stay in the EF95 family to start (the default jumper setting), and picked up some better power tubes (though I haven’t used them yet) and a couple sets of driver tubes (the smaller ones in front that really affect the sound).

Little Dot makes a nice tube buffer between various sources

Power Tubes: Sovtek 6H30EBpi Super tubes with chrome pins are by far the best power tubes to use and will cost you about $70 for a matched pair

The only affordable tube amp that was tubes for the pre-amp and power

These two tubes are chinese garbage, the metallic sounding treble gets a tad tamer after some hours of burn in but still junk

If anyone knows of some good tubes that work with this amp please let me know.

I might come back and edit this review when i receive the better power tubes (larger tubes), it suppose to yield a bit of more output power

Then I turned up the volume on one of my fav T swift songs and was SHOCKED at the transformation the song went through upon passing through these vacuum tubes
