This vacuum tube with its predecessor, the 6C15-PE, appears in all probability, in the late-syxties/early-seventies. This valve is a perfect replace for tubes as 3A167M/CV5112, WE437A, EC8020. Since the introduction in my web site , in 1997, code named by VT-W to avoid economic speculations ( in Europe for example a 3A167M matched pair can brush 250USD) this tube has gained an excellent reputation in the advanced DIYer circles and for very good reasons because the application fields are wide and stimulating:
· RF: Wide Band Linear Amplifiers from DC to 80MHz
· High End Audio: Monotube Single Ended Low Power Amplifiers, Driver Stage for 211/845 SE Amplifiers in Two Stage Configurations, Headphone Amplifiers, Line Preamplifiers Transformer Loaded, Small OTL’s, A2 Class Driving, Impedance Matching
· Pro Audio: Vacuum Tube Amplifiers in Low Impedance OTL Balanced Lines, High Current Vacuum Tube Drivers
In the next I present the full data sheet inclusive of a good Pspice Model.

The sonic performances of 6C45-PE vacuum triode can be astounding in very simple designs.
This section shows possible solutions of ’45-pe triode with PAEng Magnetics: a series of C-Core irons specifically designed to obtain the excellence in sound reproduction with high-perveance, high-s triodes. Design target was simplicity of building and low costs.
The Schematics to follows represent the results of a three years design/benchmark activity. Please keep away concerns about the plate voltage of ’45-pe triode wich works out of the maximum ratings regularly. I’m monitoring a bench where a 6C45-PE triode pair works at maximum plate dissipation with 250V; within 6,000 hours of burning I have noticed no alteration and/or spreading in the electrical parameters.
