With much worse IMD performance then the 4CX1500B.
The IMD is similar to the 4CX1000A.

The other excellent tube that's actually still in current day production as
opposed to surplus NOS status is the Chinese FU-728F that's conservatively
rated at 1200 Watts plate dissipation. A pair of these tubes in parallel
will not disappoint. It's kind of like an Eimac 4CX1500B on steroids but
with improved Po and IMD performance.
