What about unsymmetrical clipping?

[revintage]

I am at the moment building a source-follower with a P-channel MOSFET with a choke on top to drive 8ohm. This will be driven by a DC-coupled Pass-style driver.

Due to the fact that the choke(1,7ohm RDC) isn´t ideal this leads to unsymmetrical clipping. It runs on close to 2A/25V. As we run it choke-loaded the chosen B+ should correspond to ca 40V.

Personally I always want symmetrical clipping but this time it isn´t doable. Of course one could add a resistor at the MOSFETs source but this leads to unwanted high Zout. I could accept 0,5 ohm but not more.

Any thoughts about clipping in this case?

Your description didn't get me very far Do you mean like an upside down Pathos? Maybe a pic would help

Reminds of this from my earlier thread. As I said, a P-channel with choke on top.

After thinking about it a little more it should look like 2nd-order distortion just before and at onset of clipping. Symmetric should look a little more thirdish.
