I'm guessing from the way the rotational force changed on the hand-cranked dynamo that the two thyristors are being fired in sequence. The first one to attempt to fire the connected charges, and the second to shunt the capacitor via a resistor to turn both thyristors off and make the output safe on each firing cycle.
This device is very pleasing in so many ways. It's a proper blasting unit and feels chunky and functional. It can handle between 1 and 100 detonators wired in series, and uses just under 1000V to ensure a high enough current flows to trigger them regardless of circuit length or resistance of connections. one nice feature is that it has a built in resistance meter to give an indication of the circuit integrity before actual firing.
Here's the manufacturers website, but note that their products are not really aimed at casual users. Their main markets are quarries, mines, demolition and military applications.

Woah what a dinosaur!
Beethoven exploder: bom bom bom booom! 😅
A sticky unpleasant explosion eh? Hmmmmmmmmm?
The reason to use crimps is because the firing circuit will take weeks to set up, and you don't want British weather getting into the connections, loosening screws, weakening twists, etc etc etc. Everything must work first time!
Shite that made me jerk when they went bank LOL, funny.
Cute kitties, tuxies are so fun.
The serial number is BLST69… blast 69 lol
Oh great, more mad scientists out of Shropshire
Big Clive’s patent ‘cat-away’ device.. 😁
should have called it 1812 Overture
Today I learned that I seriously misunderstood what Beethoven's 7th is.
HA! How did I miss this one so many years ago. I think you had another splody box somewhere.
Cat herding with our friend Big Clive.
That was awesome and even better that you made things right again with our little quadruped friends.
Thanks Big Clive.
Pyro go BOOM.
Cats go ZOOM.
