Doesn't look too bad... Since you are using a dry transformer, you must be also using some type of current sink. A large capacitor, at least .47 uF, tied to the base of a Darlington, will stabilize the circuit at the lower frequencies. It will help make your sink look more inductive. Otherwise your sink will be contributing a significant parallel conductance. Should help the low end THL by a few dB.. Eric Petitpierre Pulsecom Herndon, VA [email protected]
