LITTLE BEAR T8-1 BLACK Moving Coil MC Step-Up Electronic Transformer
Notice: this is Electronic Step-UP Transformer, I design it setp-up the voltage by FET (field-effect transistor.), no by the true transformer.
15-Sep-2015,Upgrade to Ver1.2 now, fix the hum noise for some of MM preamp. in this Ver1.2, it's support for all MM phono preamp. and with good sound. no more loud hum now.
Something main function of this product:
This is a Electronic MC setp up transfoemr phono preamp. finished at 26th-May-2015, first version1.0, it's support MC(cartridge)type turntable only.match Cartridge impedance range: 20~100 Ohm. so.make sure your turntable is in that range.,I design this one for my T10 MM phono preamp, at before. there were so many buyer asked me to build one like this T8-1, and now.I've just finished it. you can perfact use it with my T10 phono preamp, upgrade your MM preamp right now if you has a MC turntable. also. this T8-1 also can work with your other MM phono preamp. no problem.. because it's output impedance :3~8mV at 47 kOhm / 100-300 pF ,just same as the normal MM turntable ,and i use many HiFi Electronic component on this product. Metal film resistors,ELNA Capacitance,gold RCA interface,. sound is very good. very low back noise. and sound is very clear. else, this preamp use Aluminum metal case.with BLACK and SILVER color for choice. you can pick correct one match for your other amplifier device. best quality.and nice look.you will like it.
in the end. when you got the product. and test it after. if you have any suggestion. please let me know. i will keep the good idear. and upgrade it in next version.
