Quick guide:
It's new version,first time sale on Ebay at 24-Jan-2015,I think I must say something sample parameters about this headphone. then you'll know what's it and how it's work and match for you or not.(by the ways. sorry for my bad English)
First: I must tell you that. how is this headphone amplifier design. Actually it's tube buffer + amplifier work model.both function is alone, the music input to 6J1 tube buffer preamp and output to daul NE5532(TI)(each chip for each channel) amplifier part, after music output to your headphone. else ,In back of the P2-1. you will find a OUT interface. that the 6J1 buffer preamp pure output.you can use it as a buffer preamp for your other power amplifier, that's interface music isn't through the headphone amplifier part.so. it's very helpful for install it in your home audio system too. get more warm sound.
Secondly: this P2-1 powered by 12VAC, and this list included a transformer already. with both voltage for choice. 110V or 220V,i will sent correct one to you by your order address. Outside shell is made by aluminum, good quality. P2-1 support power to 12~200ohm headphone. so. make sure your headphone is in this ohm range.About the tube.. each tube for each channel. and the tube will light up when turn ON.because there is a LED under the tube. about the tube itself. inside the tube. also will light up. but just weak light. that's normal.don't worry about that.There are 2 headphone interfaces, there are 6.35 and 3.5,Both interface are in parallel connect.so. if you want to get best sound. don't plug 2 headphones in them at same time.
