Now, What *I* think might be happening (on the first two new starters
at least) is they initially start and run the tubes (two separate
fittings) ok until everything warms up, when the voltage across the
tube increases slightly, causing the starter to re-trigger and the
tube to blink off and back on again. This process is fairly repeatable
(it might vary between fittings) and the blinking get's worse if
left.

Is it just duff (weak) starters or *could there* be something else?


Remove the starter after the tube is lit and see what happens. The
starter is a one shot process. Once the tube is lit it has no further use.
