Nakamichi TA-4A Stasis -balance issue

[gsc975]

Hi, my Nakamichi TA-4A Stasis has a balance issue, the right channel sound louder that the left channel, with the oscilloscope I checked and the issue is the in Tone board, the input signal enters equal on both channels but at the exit to the main board, the amp board, the right channel is louder than the left, I have read some posts in these forums and I saw that some users have been working on giving service on Nakamichis, so I hope someone could help me to find the issue, I measured all the components in that board and all the values seems normal, In a post on these forums read that the culprit could be a resistor that heats and give wrong numbers, so I hope someone can help me.

I forgot, the display just don't turn on too, and the led on the phono button when I press it it turns on briefly then turns off, so I need to fix that issues too, thanks for reading and help me.


thanks
Jerry
