NAD's part No. of models 3240PE/7240 according part list in the service manuals (Breaker BK1, 2) are the follow :
"0045—400—0—00" or "0045—401—0—00" or L422Y001H01 or L422Y001HQ1
If I go to "Google" and use this part-No as keyword, I find only various service manuals from NAD.
In the attachment, three images, first image shows a version from an older 3140PE and the second and third image a version from a newer device of this model.
Obviously there is to read still the same logo, but different type No.
Maybe one of the guys here know the associated manufacturer.
If I have the data sheet from this genuine parts, actually I must be able to find a replacement part from here:
