I was looking at the Morgan Jones head phone amp on the Headwize web page and have a question. How was the output
impedience calculated and what would the output impedience
of this type circuite be if I used a 6c19pi or a 6as7a ?

Thanks in advance,

Hi,

On the site it says calculated Zo was 6 Ohm, measured was 10 Ohm.

The output is a White CF which is a rather complex beast to calculate.

If you're feeling courageous I think the math can be found here:
WHITE CF.

Cheers,
