Replacement output transformer for Zenith 5S29
#2

No, that would be the REFLECTED impedance of the speaker voice coil back through the transformer, and is a result of the ratio of primary to secondary windings of the transformer. First, you will need to know the resistance of the voice coil, then the ratio of that to 4000 ohms will give you that ratio. Something like this should do the job. https://www.tubesandmore.com/products/tr...output-8-w

Yep. 10W is probably enough. Also, if the meter measures Farads, then it should also have that "Delta" button...morzh — 02:38 PM
