In serial numbers 101 to 7600, the 531's L-C [[delay line]] is before the vertical amplifier.   
In serial numbers 101 to 7600, the 531's L-C [[delay line]] is in the middle of the vertical amplifier.   
In serial numbers 7601 and up, the 531's delay line is between the vertical amplifier and the CRT.

This change was the result of [[John Kobbe]]'s insight that if the far end of the delay line was an open circuit (which the CRT approximates),

This "single termination" approach made it possible to do away with the output chassis.

All Tek scopes using a lumped-constant delay line went to this topology.
All subsequent Tek scopes with a lumped-constant delay line used this topology.
