Anyway, should I just crank up the voltage to 230 in the hope that it'll
blow altogether and thus be obvious, or is that going to cause collateral
damage (electrical damage I mean not actual physical damage)? I've tested
all the caps in circuit for ESR and capacitance and they read fine, so
this must be something that only materialises at close to working voltage.
I'm all out of ideas. Any suggestions?

Feel the capacitors and find which one is getting hot. An IR heat gun may
be better to keep the shock hazzard down.
