Power supply specs for AR11 adsl router

[#1]

I have an old aceex AR11 adsl modem/router as supplied by Freeonline back in 2002. I haven't used it for a while as its power supply failed and as I had a speedtouch spare I simply replaced the modem and threw away the duff power supply.
Now I want to try the old modem again but I can't find any information on its power requirements.
Anyone out there who's still got an AR11 and can tell me what their power supply is rated at?

a quick Google search came up with 9V AC 1.5 amp

Thanks, I spent ages googling. Where did you find that?
AC is unusual. I'll take the unit to pieces & see if there are any clues there.

Most equipment that uses a power brick should state on a label or by the power connector what the power requirements are for it.

You would think that but no, it just says 'Power'.
And there are no clues on the PCB either.

I got a copy of the manual from linky device manuals

Ah yes, I've been there. That's the manual for the A2R11, but no matter, at least it's in pdf form. The manual for the AR11 is a self-extracting zip file that is corrupted so it can't be opened.
I've found a 9V AC power supply on eBay, it just happens to come with a BT Voyager 190 ADSL modem so that should sort me out for less than a fiver anyway.
Thanks to both of you for your help, and one day I might get my adsl speed back again (currently 730kbs, used to be reliably over 2200kbs).
