[QUOTE="Ampdog, post: 80841, member: 144"] Sorry, F_D, ...did not look here recently. Yes, I will PM you. As said, it concerned the NFB components in the main amplifier section. Several tens of cycles of damped oscillation on a square wave can be reduced to almost nothing. It is also stable with loudspeaker load up to 'no load', which reassures where loudspeaker impedance may go high at high frequencies. Lastly, I changed some of the rediculously high value coupling capacitors forcing use of electrolytics - I don't think one needs to consider going down to < 5Hz! [/QUOTE]
