Please Help,


I finished TSE with 300B. The filament voltage is 4.88 and 4.90. I get sound from both speakers, however the output tubes runs cool, and left channel have distortion. The tepmerature is about 50 celcius in left chanel and near to 80 celcius in right. The right channel sounds very well. I swap output tubes, transformer as well and input tubes and the left channel have distortion.



In advance for your help, thanks.
