I have acquired a batch of these very rare US military valves. These are the type Musical Fidelity fit in the X10 v3 tube buffer and kW 500 integrated amplifier, Musical Fidelity’s highest performance tube to date. It’s more linear and quieter, with better performance capabilities than either their highly regarded Nu-Vista or Tri-Vista tubes.
This batch was made in July 1985 (22 years old!) and each valve is sealed in its original bag and carton. Never used, absolutely 100% NOS.... for use in the £3995 kW 500 Integrated Amplifier and the X-10 v3 tube buffer.
I have limited stock of these so grab a pair today before they all run out!
