Thanks. Your note helped clarify a couple of misconceptions I had about zobels and crossovers, etc.
The one remaining issue (perhaps it is a misconception too) that have is related to my original question which now, might have to be re-phrased. It was that an amplifier with a transformer can drive speakers (woofers with a zobel) easier because their impedance is more linear. So it was because of this that I asked about zobels and an otl amp.
But it seems that the hidden issue is as you say, about crossovers and not about transformers.
So it appears in fact that any system with a crossover would benefit from a zobel because of the effect that the zobel has on the impedance of the woofer as the frequency increases, transformers notwithstanding, and not the other way around.
If the above is correct, then thanks for the clarification.

You may not have an output coupling cap- many OTLs don't. - Ralph 10:27:02 05/11/23 (7)

You'd really have to build and measure it - Ralph 13:56:11 05/12/23 (0)
