I built just like the schem shows it. Does that show any feed back?

Is it the schematic linked below?
If so then the 22k resistor with the 68mmf cap across it connected between the 16 ohm tap of the OPT and the cathode of the first stage is the negative loop FB line.

See link in OP.
There is no feedback loop in that one.
Just some local current feedback on the input stage because the cathode resistor is not bypassed with a cap and of course the split load phase inverter stage (that relies on current feedback to work properly, just like a cathode follow stage does).
