tube rectifier question
hi,
nice drawing? the cap indicated is optional. if that cap is not included does that mean that the indicated resistor is left out too? i have both resistors but not the optional cap and i get 0 volts at B+ but 300 volts infront of the first resistor and 150 after it. the bottom leg goes to ground this recitifier circuit is in a preamp |

Yes. It is the cap and the resistor that make the filter. You can use a resistor there to drop the PS voltage if you want, but it does nothing to filter the DC.
