A video filter switch was added to the later SNs (1971 Catalog).

The 3L5 is based on the swept-frontend design, where the first local Oscillator is swept for the spectrum scan.
 
It is a full semiconductor design except for the final output amplifier, which uses a [[8416]] vacuum tube.

The 3L5 is a full semiconductor design except for the final output amplifier, which uses a [[8416]] vacuum tube.  The circuit is based on the swept-frontend design, i.e. the first local oscillator is swept for the spectrum scan.
