Also suitable for the Little Bear P2-1 headphone amp.
Russian Voskhod 6*1n-EB (6Zsh1P-EV or 6J1P-EV).
These are the genuine "grooved tubes" that are raved about on the forums.
Price is for one matched pair (2 tubes).
They have been tested and matched on my Avo Mk.3 tester.
Update: I have now had the chance to listen to these in a Little Dot Mk.III, and can definitely state that they sound great. Much better than the stock tubes. It is even a close run thing between these and the great Mullard M8100 (which I also tried). The Mullard is warmer, ideal if you have "toppy" headphones like mine, but the 6J1P-EV is superbly detailed without being too "solid-state". Love them both!
Here is a review from an owner on Little Dot's forum:
The most impressive tube is the 6J1P-EV. Has a very strong sound. Bass and middles becomes beautifully round, robust and instrument separation is easy. In other words: In an Orchestra the Double basses, cellos and violas become so evident, differentiated, natural and never busy that is really amazing. The highs (violins in my analogy) are laid back, some how dark, and maybe lacking of that crisp and clear sound compared to the other two tubes, but this can be an advantage in hiding the harshness and grainy sound of bad caps, bad input equipment or bad recordings, making the listener experience more easy, exclusive "musical" and less "critical" or "analytical", if you know what I mean. This tubes remind me the oldie tubey sound with a single full-range speaker, but with stronger and thicker bass. Soundstage: this tubes creates a very seductive sensation of bigger ambience (is like adding a very small spice of reverb) and that's why this tubes sounds more like a hall than a damped recording studio. This sound signature contributes to give the overall sensation of a thicker sound and allows you to hear something more than the sum of the individual instruments.
