Описание товара
Quickly guide (If you're new buyer,please take look all of text): What's different between this list and other list of T10-Pro,This is Toroidal Transformer version.also with the newest version board Ver2.5,and package 6N2 tube instead 12AX7, Toroidal Transformer instead EI transformer.that's all, other things are same. one more thing,this item is heavy. not package power cable.(if package power cable. weight:>2KG, we can not sent it out by normal register mail,please understanding) One more think you must to know, this item PCB is finished and all electronic components are already soldered. The panel box and transformer, you need assemble by yourself to complete the unit - easy work! Upgrade log: 25th-Dec-2014, we just solved the hum noise problem. now. the sound is very quiet. I promse~. and add a new option function,output GAIN option. you can set it "LOW or HIGH" output.about some of buyer already brought this item before. you also can buy the part to upgrade your phono preamp. NOTIC:This preamp is using for MM (Moving-MaganeticCartridge) turntable only.do not support MC truntable, also not support CD or other similar player More information of this phono preamp. you can google it. not let you know down, else. if you have any suggestion for this preamp. fell free message to me. i will keep it the good suggestion. and upgrade that function in next version. 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! 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 10~20mV,MC source is 3~5mV,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). If using express shipping model(FedEx EMS), the shipping fee is expensive too, so it's not as cost efficient to use metal case. Metal case is available for a few counrtries only, but I think I need to share this preamplifier to more fans like me and that's way we use the acrylic panel, this way the unit can weigh less than 2KG. If you're a DIYer, you can build a metal case by yourself. we can provide the dimensions file to you:) I'm pleased with my design - I hope you enjoy it.
Focus:
A,Design a new acrylic case for the pre-amplifier,it's looks more nice then just 2 panel version. and more safe too.if you have a children at home. :) B,Re-design PCB. now, it's support 2 model tube, you can using more tube for it, and get different sound, current support 6N2/12AX7 tube,you can find more replacement tube for it too.for example:6N2 can replace 6H2,6H2n, and 12AX7 can replace:12AX7B,6N4(9PIN),ECC83,5751....more, 1. It's a pure valve phono preamplifier. Sound is warm and classic, clearer and truer sound is restored. 2. Using 45VA customization Toroidal Transformer , low noise. 3. Coupling capacitors all using HiFi WIMA audio capacitor, best model. Very low noise and clear sound output. 4. 3x 6N2 tube(low noise tube) +1x 6Z4 tube.RIAA phono stereo
the transformer with 110~120V and 220~240V both version. i will sent correct version to you by your address.
