Burned out strobe tubes

Lets assume we have a one-channel strobe. It has two lamps (in parallel). If one lamp burns out, does this typically cause the other lamp to more quickly fail?

Situation: I have a two-channel, 4 lamp circuit and all 4 lamps test to be bad. It just seems odd for all 4 to have failed.

(The trigger connection is obvious, and I swapped the anode and cathode just in case I hooked them up in reverse. Using a known good 9M4S supply.)

Come on, I know this is old technology, but some of us are pretty old, too.

Doesn't anyone remember Xenon strobes?

An answer I would expect from Joxer...

Very unusual to have 4 strobes go out at once. The culprit has to be
the power supply. When one of my Edge 9000 or 9M bars comes
back to me with 4 strobes out, it has always been the fuse at the
power supply or the power supply itself.

It seems to me that it is just too much of a coincidence that all four were bad. I have taken the lamps out of the bar and tested them on a known working 9M4S power supply.

Confirm that I am thinking correctly on this: the terminal with the orange arrow would be the trigger, right?

And I've reversed polarity, in case I can't tell my cathode from my anode.
