Hello I made a test with help of Torpedo and Picaudio (Thank you guys). I'm sending a calibrate signal from my PC and DAC (1Khz and 1 volt) to I+. On the O+ I just check 0,0791 volt. If I send the I- to ground, I check 0,0500 volt. I would like post photos of my work. Thanks

Thanks Dr. Gilmore. Sorry, I forgot give you the settup of my amp. My Dynahi used two Sigma 22 with two toroids (160VA each one). The output volt. is 29,5 Volt DC. I followed the Ti Kan´s guide for settup. The Bias is 0,75 Volt, the working temp is arround 70º centigrades. I had problems with the offset setting but now it´s controled. I´ve used my DAC with balanced output and I checked some Input configuration: Balanced input with SE output (I used the O+ and PSU ground) SE input with I- to ground with SE output With those options the sound is very poor and the volume is "minimal" but with balanced input I believe that the test is a bit best. I use for dummy test an old AKG. If you need more info, photos or other check/test, I can post in this thread Thanks Edit for error, sorry

Hello everyone. It´s my first post here and I need a bit help, if it´s possible of course. I have got a Balanced Dynahi (Tran´s boards, using the THAT340). I just finish the amp and set-up but I have a problem with the output: I´m using a SE input with Input- to ground and output- floating. The sound is very poor and the volumen is little. With balanced input and the output- floating, the result it´s the same, poor sound and little volume. In this time, I haven´t volume pot. Have the same problem? Thanks
