Just got a X-101-b and after some cleaning and a little work the thing sounds just awesome, have not hooked it up to my speakers yet but been using it with my AKG-240 high impedance headset and its an unbelievable sound, I must say this is my first experience with tube audio.

Im looking for specs for this amp, there is not much on the net about it, so I will take any info, input, experiences etc about this amp.

Thanks all....Gil

This may help

Here is more info, specific to the X-101-B
