I finally got a triode model working in LTspice so I thought I would play with a passive BP filter implementation. In general it looks right except that after the output buffer (CF) the HF roll off flattens off while the signal at the grid continues to fall as expected.

Any idea why this would be?

Schem in this post, output results in next one.
