Cordell, Roender and other Members have reported on testing of the diodes.

Thanks , do you have a link to that thread ?

In that case, IIRC it was posted by Charles Hensen in one thread. I feel u should search for in his posts.

Simple modification. The operational amplifier increases the useful signal 0dB, 30dB signal the error. In conclusion, the bias decreases 20dB

Anyone know the dampingfactor on this amp?

Damping factor is dependent upon load impedance.

If you don't specify this your question cannot be answered accurately.

Ok,the speaker has 8 Ohms impedance and 5,1 Ohms voicecoil.
