I am trying to verify Input/Output impedance specs on a 1965 Hammond/Gibbs spring reverb tank with the part number 25-0005 on it. Google tells me that these were used in some Hammond Organs. The one I'm dealing with has an input DCR (resistance as measured with a DC Ohmmeter) of 1.2 Ohms, which corresponds to an 8 Ohm input impedance. The output transducer winding is open, so I can't measure it.
Any help would be greatly appreciated. Even better might be if someone happened to have one of these tanks in their personal boneyard.
