Description
Two versions of the same U12 valve with two different Marconi decals.
The Marconi U12 is a directly heated full wave rectifier.
Audio Magical shows the most successful U12 made back those days.
The two pairs you see here have elegant design, same shape and construction with ST fat shape and mesh plate as well as full getter.
The Holy Grail of audio valves.
Best rectification.
All four Marconi U12 have been tested at 4 Volts filament setting at full emission and working order that is to say this quartet U12 Marconi tested 100%
