I am replacing an output transformer on a model 650. I have a Hammond 125E output transformer. I'm trying to determine which lugs to connect to the speaker from the secondary. Please educate me. I'm halfway there. I was looking at Franks Electron tube data sheets page. The RCA literature for the 42 tube in push pull configuration says the load impedance is 10,000 ohms. Is this the info used for determining the correct output transformer secondary lugs? The speaker voice coil is about 1 ohm. So I would think that the secondary lugs 4 & 5 on the Hammond 125E would be correct. Is my thinking correct? Thanks for your help. Dave
