Might be a simple question for experts; but I'm not one of those.
My beloved loves fairylights and I need to resting the lights for next weeks party but the PSU's for half of them have died.
The little sealed units are marked as 240V in and 31V out AC
As I have all those cheap sub amplifier boards in the shed that are not worth repairing and all have good toroids what is the easiest way to wire up a power supply for the LED strings?
No flashing needed just On/Off
Now I have 28V toroids and 42V toroids and I'm assuming that 42V is too much. These toroids have three wires, two Red and one black and are marked 28-0-28.
I build speakers so working with 240 volts isn't my strong point but I'm in a hurry to get these lights up to please SWMBO
Secondly what effect would using 42V have apart from making the lights brighter? Much lower lifespan or would they simply burn out immediately?
Help needed and appreciated so TIA

31V AC and each little PSU is rated at 6Amperes
Maker lable is CZYUTAI and while many are marked DC these are definitely marked as AC
IP20 not IP65 Indoor use only, although I use them outside they have always been undercover and in a weatherproof area.
The lighting chains are OK but the PSUs are dead
