7A15
The 7A15 is a single channel, 80 MHz general-purpose vertical amplifier for 7000-series scopes. The AM-6565/U (aka 7A15N11) is the military version of this amplifier. A 2002 Department of the Army Technical Bulletin (see links section) suggests that it was used with the 7603 and it's military version.
The 7A15A is a fully discrete design, no integrated circuits. It is mostly BJTs, with a 151-1032-00 dual JFET as the front-end buffer.
