Have we all stopped arguing? May I ask a question? What's the best way
to check if a power amp is likely to be stable into a capacitive load
such as an ESL? I could put a 2uF cap on the output and look at the
output on a scope while feeding it with a square wave. But is it likely
to damage anything if the amp fails the test?

The old test used to be something like a 2.2uF cap.


** Never was and still is NOT a relevant test of an amp's ability to cope
safety with an ESL speaker like the Quad '57.


But TBH you would be
better experimenting by trying various capacitances,

** Absolute CRAP !!


What happens will depend entirely on the amp design.


** And has nothing to do with Eiron's dopey question - ****HEAD
