I measured the trimpot and it is set at around 2.18K. I just noticed that the original R52 that I removed was indeed 10K 5%. Odd. I really don t understand

Went ahead and increased R52 to 3.92K. Pretty much the same. Highest E, now comes as Eb +37cents, 5.29V. Highest C is 5.96V. Then 10K, Highest E, comes as E
