Trem has too much put-put

[tubesornothing]

I put a trem on my PI, using the fender 5E9-a Tremolux circuit.

I really love it, BUT when I turn up the intensity it has too much "put-put".  Anyway I can calm it down?

Perhaps I'll post a scope shot (yippee, get to use the scope!)

Did the amp you used have a paraphase inverter?

No, it has a LTPI

A 0.1uF between grid and plate smoothed it out.
