Hi Eric,
HENRY switched from the 8877 to the 3CX1200A7 because:
The 3CX1200A7 is instant on (no warm-up time).
The 3CX1200A7 is lower cost.
The 3CX1200A7 has a more rugged grid.
Many people love the 8877 (I do too!) because it requires less drive to get
1500 watts output and is a reasonably rugged tube.
HENRY may make something in the future using the 8877 again.
