Allen,

From the article the Zoebels are 100nF in series with 10 ohm, they are for high GBW (global bandwidth ?) solid state amplifiers.

Thanks again. My client will try this.

A Pass 250.5 should fit the description.

Regards, Allen

The Zobel is mostly needed for bipolar output stages as these are sensitive to RF captured by the speaker leads. Can't remember a mosfet amp (as the PL are) with Zobel.

Have fun, Hannes

Well said!

This is especially true since the designer is rather generous with his time and experience.

I don't have a connection for him, but Nelson was the first replier, but gave no advice then or since.

And I'm not claiming a faulty amp, just the combination of amp and my speaker cables.

Actually I have given advice twice now.

It's OK with me if people bring up a service subject here, as
long as they don't use it to annoy me.

I never saw your second reply. Apologies.
