Greetings Doc, In a back issue of Valve, you describe the active load. Can the active load be substituted in for most plate loading resistors? I am going to crack open my Jolida once again this weekend to remove the negative feedback. While I'm poking around in there, I am going to find out the values of plate loading resistors used as well as the voltage across them and current through them. Would you be able to use these measured values to choose the appropriate component values for a C4S active load? (DC resistance, current through resistor, voltage at trannie and voltage at the plate) Thanks for your time and have fun, |

Looks like it can be done unless jolida drives the piss out of the 12AX7's and 12AT7's. I'll find out this weekend. Thanks and have fun, |

Oops. That 52K 1W resistor ahould be a 38K 1W resistor. The additional bias current of the C4S will create a 3.7mA draw, not 2.7mA. |
