Hello folks:
I have a quantity of Y398 tubes NIB (circa 1966) and would consider
one or more in a medium power  amplifier I am planning to build if I
knew what they were. My tube library doesn't list them and Eimac has not
responded to a request for data sheets. They look like 4X150A's. Can
anyone help me with this? Thanks.
