MKII.That said the G.E. tubes were by far the best sounding driver tubes out of the three pairs I bought and they were also by far the cheapest

They are by far the cheapest price point and they are also the best sounding driver tubes I could get my hands on!

My buddie also bought all the tubes I mentioned as well as a pair of Vostek and a second but different pair of Mullards to see if they could top the G.E's and not a single matched pair out of 5 different pairs of tubes could beat out the G.E. tubes sold here for $20.So to save you the trouble of guessing at the best driver

I didn't think these G.E. tubes would be any good as driver tubes and planned on using them in my Tube Buffered Nobsound Preamp that allows me to use tone controls with my Little

Hope this review helps out a few people looking for the best driver tubes and ignored these because they are G.E. tubes from America, where tubes are not known for great sound

Great replacement driver tubes for the 6J1 pair that come with the Little Dot Mk II.
