Plate Voltage 700V
OT 100W 6KOhms primary (Plate to plate impedance). Secondary 4 and 8 Ohms. I
Tube in pentode config, as 6L6. I changed the decoupling capacitor of output stage from 0,1uF (normally used in Fenders) to 0,022 as in Marshall 1959 model (plexi). The ampli was super super bass before change de capacitors. Bias voltage is -35V and tube current is 40mA (for each tube). Problems with NF, as related in other post of this section (ZZZZZZZZUUUUUUUUUU). So I don't use NF. I have the same problem wih a Plexi 1959. I don't know whow to fix this problem. The ampli seems stable and works well. Very loud. Good lucky, and let me know you experiences if you built a prototype.
