Description
STC was established in 1883 as an agent for Western Electric USA.
STC was based in London.
STC made several valves under the Western Electric patent and the vast majority equals the sound of the Western Electric itself!
There are WE 300B and STC 4300A on the triode section of Audio Magical
Showing a pair of early design STC 274A with UX4 base and red print on glass.
Black plate with full D-ring getter for the F made and square getter, the holy grail of audio valves!
Make no mistake these are the Real McCoy!
