If they produce more power and less drive, they can hardly be termed
direct replacements can they? The 8877 are sold for industrial purposes.
They are not made just for hams.
Sounds if they are more than a bit dissimilar. That's not to say they
won't work in a particular amplifier, but I'd hardly call such a tube an
8877 or 3CPX1500A7. Steve says the size is different too.
In any case, and 8877 is *not* a 3CPX1500A7 - its an 3CX1500A7.
