Got tired of ugly wires...
The best op amp I have found so far is the MUSES 02.
I realize that some people on this forum are intimidated by the thought of making up adapters to fit tubes that were not originally intended for the Little Dot amps. Personally, I was myself very hesitant to fiddle with the electronic stuff since I do not have any background in this. However, once you decide to try it is not that difficult, especially with the excellent wiring diagrams provided by the esteemed members of this thread.
If there is an interest, I would show in pictures how to put together an adapter using a 9 pin breadboard socket and Vector adapters for those who are new to tube rolling and want to use non native tubes in the Little Dot MKIII amp. As I learned through Gibosi, this can be done without the use of a soldering iron.
Hi All,
At the present time I am exploring different 6SL7 tubes. However, first I want to say that I have been listening to a bunch of tubes from the 6DJ8 family, mainly different brands of 6BC8/6BZ8, 6BZ7 and 6N23P tubes. The amazing thing is that all of them are very good, with the trademark etched detailing of sound, wide sound stage and good bass and treble. The only con is that they are a little cold and analytical, but not in an irritating way; just the way they are, in a pleasant "intellectual" way. These variants probably offer almost all of the sound of the very expensive Amperex tubes at a fraction of the price.
Now back to the 6SL7 tubes: In contrast to the 6DJ8 family these tubes are warm and musical. Some of them lack in the detail but it is made up by the musicality and heft in the bass that can go very low with some of these tubes. My favorite right now is this 6SL7GT Tung Sol tube from July 1967:
This tube has a very sweet, warm sound, excellent imaging with great bass and mid range. What stands out is a fat mid bass. The treble is not sizzling, but still very good and satisfying. The slam and attack is lesser and slower than the 6BC8 tubes, but as said before, this tube makes it up with it's musicality.
The tube is shown in action mounted to a breadboard wired for a 12AX7 tube with an octal adapter. The multi colored wires come from a discarded computer power supply.

Happy tube rolling and listening!
Speaking of adapters i started to put together an adaptor for octal tubes since my chinese adapters are probably lost ,using Troll Dragon's design and Artsi's schematics here's the 12AX7 an 6DJ8 adapters i made heres a few pictures the 6SL7 octal adapter is more elaborate since theres cutting and soldering i would say just for the chassis i will probably put in a couple hours since i have to open up the diameter where the octal socket goes in the tube .as for the rest the parts used will be like the other adapters

That is nice, what gauge is that wire you are using(solid and the stranded)?
22 gauge stranded copper wire for the connections and 1 m.m.(.039) copper wire for the pins
