I think I will first get that transformer I ordered today, it is a pushpull OT20PP from Musical Matt, whose 8 watt SE I successfully used for my Zenith.
The OT20PP is 6K6/8K to 4/8/16 Ohm so I can match my voice coil to the tubes' requirements pretty close as my coil is 6.2 Ohm and so the impedance is somewhere there. And I know this is not the cone or the coil or alignment by now. So when I eliminate that I'll see if I want to putz with it some more or I will be content with authentic working radio.
