ESC for Madrat - HELP

[mosqui]

I have got no power in my Madrat, so I guess the ESC is not working, but here in Australia it's not easy to get parts. I was reading about the hong kong based suppliers but they don't have ESCs, only plastic parts. Then all the ESCs I found are mainly for brushless, which I'm trying to avoid at the moment as I'm happy with my brushed motor at the moment.
Any other solution for my ESC? I have a Sirius SE2. Can anyone recommend any different brand or type? I saw a Tamiya 1048, but not sure which motor I have and if it going to support it.

Thanks in advance
