Astec AA16330 (or equivalent) PSU for GP340 6way charger

[squibby]

Hi,

I've got two 6 way chargers in both of which the power supplies have gone bang (bizarrely back from the different jobs, and within hours of each other but otherwise seemingly unrelated).

The PSUs are Aztec model AA16330 which are rated 10A at 12.5v (125w). I've googled this but can't find anything other than PSU repair services or an expired Australian ebay listing.

Can anyone point me in the direction of two replacement PSUs?

Many thanks.
