Best made Valves/Tubes in the world

What are your fav tubes?..I’ll leave this here to start with from Watford Valves…

Probably the best made Valve in the world!!!

The 6C33B-C was designed to regulate the radio power supply in the Russian MIG-25 fighter Jet. It was made to withstand an electromagnetic pulse attack and the severe g-forces put through it whilst flying.

In Audio amps the Ulyanov made item is a sensation.
