Differences with 6C33 Tube Types

There is 6c33c and 6c33c-B. They are the same, but the tolarances are tighter on the 6c33c-B.

The 6C18C should be a drop in replacement for the 6c33c, but the construction is slightly different, so there should be an audible difference in most circuits. These tube types are rare, and very few people have got to mess with them.

The 6C41C is electrically like half a 6c33c. But the construction is not the same as cutting a 6c33c in half. Its internal structure looks more like a shrunken 6c33c. So it probably won't sound identical to running half a 6c33c.
