They should be inside the small plastic envelope also in the box.

Hmm. I would then open the bottom and see if they're already installed. Check the instruction manual as to where to look for them. They're VERY small. If not there, they should be readily available at a nearby electrical or computer source store. but you'll need to know what they look like!

You can download an English users manual here - Viewing a thread - The Little Dot MK II Headphone Tube Amplifier/Pre-Amp. Look at the bottom of the first post.

Also, email David about the missing jumpers or find a suitable replacement locally.

Just an FYI, The jumpers are the standard size, so if you have an old computer motherboard or any old computer stuff, the jumpers used there are the same type/size, so you can get a couple that way. Radio Shack sells them as well.

On the MKII, you have to remove a few screws to get to the jumper pins. Notice you have 4 screws on the front, and 4 screws on the back. Remove the bottom two screws on the front, and on the back, and the bottom of the case will come off.

Look at the exposed board. You'll see the jumper pins located more toward the front of the board. Simply install one jumper on each set of pins (one set is Left channel and one set is Right channel) and then put the bottom of the case back on, and screw it back together.

Now you are ready to try the EF92 family of tubes.

I think you'll like the EF92 family. They are my favorites.

Yep, and they are good ones too.

They'll need 40-45 hours to mature, but you'll notice their nice sound right away.

i noticed on the maplin electronics site that they have 2.54mm jumpers(10 for 99pence) would this be what i need?
