Supreme 546 Oscilloscope  
Written by AnubisTTP on 2006-09-24  


The Supreme 546 is a military-issue vacuum tube oscilloscope built in the 1930s and 1940s. The 546 is notable for its relatively massive 3" display, three times the diameter of many scopes from the same era. Internally, the 546 is exactly what one would expect from a piece of equipment of this age. The underside is a mass of tar and wax paper capacitors; topside there is nothing but tubes.
