The Moog 911-A Dual Trigger Delay provides two trigger delays from 2 mS to 2 seconds.  The two delay sections can be independent, in parallel, or in series as selected from a front panel switch.

Even though this module is from 1975 it still has the old R. A. Moog label.

This module now has a circuit board instead of the hand-wired perfboard construction.

Note the parts placement is rotated 180 degrees between the two independent sections.

Operation

I calibrated the delay at the mid-position 1 second setting.  There are scope images of the Dual Trigger Delay operation on the three cabinet Moog 911-A page.
