Hi Gang,
I am trying to identify these items for a friend. It appears to be some sort of tube substitution device to me, but that is only a guess. It appears that the Army green, 7 pin plug-in device might be intended to plug into where the minature tubes are located.
Both items have the GAP/R code designation so I am assuming they go together.
Have any of you ever seen one of these before?
Never mind........I should have googled it first. It is an op-amp
