| Choke |

| Second capacitor | |
For a total (C1 + C2) capacitance above 33uF, a limiting series resistor must be used, so the peak in-rush current through the choke is limited to 1A. Otherwise tube damage can result. MUST MEASURE. Can not be calculated in a reliable way. For lowest hum, this resistor is in series with the choke. So you get a C-LR-C filter. In this way 200uF is possible. |
