I have discovered the culprit! After another trip to the patient and perseverance, the overtone issue has been rectified. Here is a list of what it was not: sympathetic vibration through plate strut, leaking dampers, lack of stringing braid on N/S length behind bridges (although the application of same did help in overall tone), damper(s) resting on node(s). Any voicing technique which involved manipulating hammers. So as I sat, played, and pondered I recalled a comment from the Busby/Mrykalo voicing class - "String prep will cure a lot of voicing issues." So the winner......tweaking the termination of F2 right hand string at the front bridge pin. A flick of the wrist and immediate results. Which makes one wonder why I didn't do this weeks ago. 🤷🏼♂️

David... he stated it was a Yamaha GA1 and the note was C7 . I think this is one of the smallest Yamaha Grands and may be the one that was rescaled.
I recall working on a small Yamaha that did not sound any better after being tuned. I have also found some Yamahas to have some bell sounding strings in the bass that others suggested to add magnets on the plate struts to increase plate mass. Weaving some cloth on the back scale/nsl may help along with some magnets.

Are you talking Yamaha C7 or the 7th harmonic of C on some other instrument?
Best wishes

Hello again,
still battling the c7 overtone. Have methodically applied aforementioned ideas, excluding voicIng, at this point. My next step is to go through and check if there is a damper resting on a node somewhere. With that in mind does anyone have a systematic way of checking Damper/node interference?

I just had a Kawai KG-2 and a Yamaha U3 that had nasty plate ring. As I got into the bass tuning on the Kawai, it really started to ping. I tightened all the plate bolts on both pianos and the pinging went away. The head of the school noticed the improvement in the bass from the other room. I have solved many nasty overtones by checking and tightening the plate screws.
My U1 that I got from burning man had 2 stripped screws when I checked them.

Have a Yamaha GA1 which has a nasty overtone ring at C7, but only when you play F2.
Have checked damper seating at F2, and elsewhere along the overtone series.
any help taming this beast is greatly appreciated
