>> And not all OTL's are cap coupled on the outputs...
Yes some use a servo to zero the output voltage.
A can of worms that I would never ever try ...
If it fails you blow the speaker - no thanks.
If they don't use a servo then the tube varies
as it wears out and then blows the speaker -
again no thanks.
Any use of feedback isn't for me.
I can't stand servo's in subwoofers
let alone the upper frequencies.
I also like to over-design things
so that they do not go BOOM 8^D
