Conversion of Hiraga's "Le Monstre" to a Circlotron

tiefbassuebertr · 27th June 2009, 10:41 AM

Hallo together

the original circuit is mirror symmetric between pos and neg halves (so called "true complementary push pull") but in real life I missed the symmetric behavior - see foto about clipping
"Photograph 6: Stability at Clipping - 1kHz into 8ohms " by URL
http://diyaudioprojects.com/Solid/Je...ga-Le-Monstre/ (scoll down, last photo)
If you compare the rising edge of lower half to the falling edge of upper half, you see the different.
Additional the 300 KHz Sine Waves are more like a sawtooth, what is bad omen (no low IM distortion at high frequencies)
How I can I convert Hiraga's "Le Monstre" to a CSPP version (cross shunted push pull)? By the output stages allone I haven't problem (there are some examples on this forum), but include the input stage I don't find solutions.
Thank you very much for your advices
