Quick Guide (If you are a new buyer, please read all the text):What's different between this list and other listing of T10-Pro?This is the Toroidal Transformer version. Which also comes with the newest version board (Ver2.5),and package includes the 6N2 tubes instead of the12AX7, and the Toroidal Transformer instead of the EI transformer. Everything else remains the same.One more thing you should know, is that this items PCB is finished and all electronic components are already soldered. You only need to assemble the panel box and transformer, by yourself to complete the unit - easy work!Also, this item is heavy therefore does not include a power cable.(If package included a power cable the weight:>2KG, and we could not send it out by normal registered mail)

This is the newest pure valve phono preamplifier. This class A preamplifier provides a beautiful and very warm sound output. Gold interface - I tested it with my old classic Pioneer turntable and the music reproduction is fantastic, better than the T9 model. The sound is warmer, clearer with a lower background noise. It will not let you down.This is the real HiFi version. If you previously owned a turntable - now it's time to revisit the classic!Weight:1.65KG, Size:256*190*70mm(10.07*7.48*2.75inch), PCB is finished and all electronic components are already soldered. The panel and transformer, you will need assemble by yourself to complete the unit - easy work!
And about some buyer respond the hum noise problem.In normal,there is some low humming noise.not loud.(because the phono preamp is amplifier the signal to about 800-1000 times,the MM source signal voltage is 3-5mV,MC source is 0.3~0.5mV,need amplifier up to 1.2~2V,(so,if any noise in the signal,it's will be same loud too.)you can try follow step to be sure is in lowest.1,Must be sure the the GND point is connect to real earth.you can test it.using your finger touch the GND point. is the humming noise come to lower?if yes.that's mean the GND cable not in good connect,if the humming noise is same,no change lower.that's good.2,Using some better audio connect cable,and move this valve preamplifier little far from power or TV or other Electric device.3,Connect the transformer case box to GND too.
Q:Some buyers ask me : why not build a metal box for this phono preamp?
A:If using a metal box, the price will increase to 280+USD, so many country's HiFi Fans cannot use it, because by using metal box, the amplifier would weigth more than 3KG, then we can not sent it by normail registered mail.(registered mail accepts packages weighing less than 2KG only).
Focus:
A,Design anew acrylic casefor the pre-amplifier,it's looks more nice then just 2 panel version. andmore safe too.if you have a children at home. :)B,Re-design PCB. now, it'ssupport 2 model tube, you can using more tube for it, and get different sound, currentsupport 6N2/12AX7 tube,you can find more replacement tube for it too.for example:6N2 can replace 6H2,6H2n, and 12AX7 can tube(lownoisetube)+1x6Z4tube.
