Hello,

My tech is having a challenge to fix my tuning. I have isolated the issue to voice 5 by referring to the service manual and disabling the voices one by one to find the culprit. Now that I know it's 5 all the time, I am at a loss what to do next. The voice always tunes too high, each tuning cycle (for the voice) a little different. Most times it's around really high, around 10~15 ct to high on my tuner, and if I get very luck, around 7 ct too high, but still way off from the other voices. My tech has done the below, work, but has not resolved the voice 5 high tuning issue. Is there anything I can do on my own, or any area I can point him to that would assist?

It's strange that he notes Voice3, while I see it as Voice5. Maybe it's simply he saw that Voice3 was the worse at the time?????

Work already done:

ChangeVoice3S/HICchip. (TL082)

ChangeOSCCVresistorsx6(0.1% selected) (100Ω0.1%)

Adjust+5.0000Vreferencevoltage.

AdjustD/Aoffsetto0.0000V

thanks,
