Looks enough for 6.3VDCout. Not plenty but just enough.Loaded 10,7VAC, it's a nominal 9VAC 30VA.
Remember there's a resistor position in the Zobel that the electrolytic termination option needs to bypass. Watch the pads configuration.I don't use remote sense, I will try to change the zobel network as suggested, thanks.
Could be the heater because it has inrush at startup overshoots the current limiter, output voltage drops, and nothing works normally for a little while until its mA current demand goes to spec.Near 800mA still oscillates, could be the issue Zobel network related, because several times the tester reads 1 or 3 volts:
