Good - I see that you haven't yet been bitten by the tube rolling bug! It is very dangerous and results in buying more and more tubes - it never ends. In any event, when I owned the LD MKIII the EI tubes were among the top performers.

30-50 hours of burn in is normal, but some tubes can take much longer. I remember reading that the Voskhod tubes need 120 hours to sound their best.

…yet …

This thread looks DEAD, but i will try, Mark 3 vs Mark 2 which is a better sounding amp ?, This thread has 227 pages, the Mark 2 has 888, is that any indication ?

It really depends on the Impedance of the headphones. The II will work best with low impedance cans, and the III was voiced with Senheisser HD-600/650 headphones. What do you use?

Threads don't really die, people just lurk.

Hi,

Is it possible to use 6SN7 as driver tubes in the Little Dot Mk3?
If yes, what do I need and which jumper setting do I need?

Thank you in advance for an answer!

As I recall you cannot use 6SN7 tubes as drivers in the Little Dot MKIII because they draw 0.6A each and the combined 1.2A exceeds the allowable current draw for drivers in the LD MKIII.

Yes, This has been done by a number of people. Go to page 223 in this forum and you will find the fellow who posted this phot. The adapters are available on eBay and Amazon.

With all due respect, RaynFox asked about the compatibility of 6SN7 as driver tubes - IMHO it will not work. As power tubes the 6SN7 work fine with adapters.

That might be the coolest, Super Mario Bros, looking adapter I have ever seen!

Would I possibly be able to buy an adapter like that for you or is that not an option? They look pretty well made

I still have these, 2 of these adapters are for use with 6DJ8 tubes and other for a 6SN7 or 6SL7 tubes , but i sold Littledot MK3 several years ago ,problem is that shipping is rather expensive and i could not test adapter before shipping .To get more infos on adapters we made back then best bet is to go to https://www.head-fi.org/threads/little-dot-tube-amps-vacuum-tube-rolling-guide.563884/
