We'd correct it, send back, and it would immediately get worse again. Tried doing it on the fly but I couldn't keep up with the scale of drift

Seems to be a possiple culprit for injector drift, note the plate's voltage has gottent progressively more noisy after the wein angle change, and the two instances of injector drift correspont roughly in time to the two current spikes. Compared to the stronger Wien setting in fig 2, were it was completely quiet all of the time.
