No there is no speaker protection.I don't like them at all.The amp is stable like a rock....
All the transistrors are matched 0-1% and the EXICON's are matched too..

Ok.
I'm glad to know you like its stability.

It's just that it's a DC coupled amp so any form of speaker protection is welcome. But I understand your point.

Happy listening!!!

I like those huge VU meters. I was planning on using similar ones in my design but I couldn't find any decent looking ones. Where did you buy these and where did you get the driver board from?

Hello guys.

A preamp/headphone amp is undergoing development. Here is the thing on perfboard and some preliminary test results. Bias 20mA. Power supply is unrregulated half-wave rectified +/-17V.

Let me know your thoughts.

More coming soon.
