There is a company near my location who replaced Amperex 4-400B by 8877 when
Amperex stopped production.
The tubes are used as voltage regulators in plasma sputting devices.
For more then 3 years I wait for pulls but since then no tube has been
replaced.
The have a total of 450 Chinese tubes in use now.
