Vintage:                 1948
Purpose:                Monitor Scope
Condition:            Unknown



Comments:
This unit is very basic. There is no amplifier for X or Y deflection. It is a basic monitor scope, possibly used with external amplifiers. The CRT is a 2AP1, a 6X5 is used to generate the sweep signal.
The name plate does not show a serial number, so this may have been a kit.
