> > ...Ra=33k, Rk=820 Ohms, bypassed with three "poly" capacitors - 10u, 10u and 68 nF. Input grid leak resistor is 1 Meg. RC coupled to 45, 2uF + 220 k (grid leak for 45)...> >The plate load is too small for a circuit without feedback, and the 3dB rolloff point of the bias network is 10Hz - way too high. Also the coupling capacitor is excessively large. 0.33uF would be more than adequate here.
