Hi revintage, welcome to TSSA thread

In TSSA Basic from post #1, Zout mainly depends on open loop gain (voltage gain if there would be no feedback present), higher the OLG the lower Zout is. If you higher 1k Rgs to 2,2k like Sonnya did, you get half Zout etc. I assume Zout is in a range 50-100 mOhm.

Regards, Andrej

Don't be fooled guys, Lazy is making CSA in the background (behind the scenes).

From what I see it is slightly above 1 Ohm (Post#1). Worse than F5. But my paralleled IRF632/9630 version has zero output impedance

Yes Sonnya, that is correct!

Jay mixed up TSSA Basic with zero-feedback transformer output tube amp.
