Yes the current draw for the HT delivered is about 160 amps max but at 440 valts or so, I think.

I was referring to the current it draws on its own dedicated heater winding @ 5 volts, and it is near to the limits of that winding on the ST20 power tyrannie, and is easily exceeded by a 5AS4 and many similar but not very well spec'd tubes.
