yes T , not TL, could be To72C i suppose, dual opamps
Does anyone know the maximum supply rail voltages. ?
I will replace with TL072 as ps fault allowed the secondary supplies to
these to go well beyond +/- 15V at some point, just wondered if they were
+/- 20V maximum. I cannot find that info in my books or www.
