The Tektronix 7603 is a general-purpose 100 MHz non-storage, large screen scope that takes
two 7000-series vertical plug-ins
and one 7000-series horizontal plug-in.
The AN/USM 281C is essentially a 7603 with option 01 (no readout = 7603N).

Internals
The 7603 was made in various versions for many years, with revisions to some subassemblies like the vertical output amplifier and HV circuits. It uses a linear power supply, a fan is optional. CRT deflection plates are not distributed. The vertical output amplifier is built around a 155-0080-00 hybrid. Other custom Tek ICs used include 155-0011-00 clock & chop blanking, 155-0022-00 channel switch, and the 7000 series readout system chips.
