Indeed you were first. I replied to Harvey's post, b/c it was longer
I'm still not convinced, though, that the theory is incorrect. Are you disagreeing with the mechanism itself (pulses travelling from left to right, and so on) or the cause that aggravates it (removing the pre-cats) ? I certainly agree that replacing the main cat (or other suitable resonator) with a Y-pipe would be even worse, but I still have the recollection (haven't gone back and re-read everything to confirm) that keeping the main cat but removing the pre-cats also contributes to this unwanted resonance.
If you disagree with the mechanism itself, is there a different theory to explain it ?
