WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Does anybody know the impedance of the OPT used in the FatMan iTube 182 amp? I have the schematic but it does not show the value. Any info would be appreciated.
