G GaryPA New member Dec 1, 2021 #1 I have a x26 with a bad hum. It appears the OpAmp ( NJM4565S) on the power board is putting 5v on the chassis ground. Is this correct behavior? I attached that part of the schematic. what is the reason to have an op amp on the power board? Attachments x26_OpAmp.png 46.4 KB · Views: 3
