A 12V *AC* power supply

[Shachar Shemesh]

Hi list,

I bought a USB connected logic analyzer for too much money (not that 
much). When buying, I did a mistake and not thought through the issues, 
and bought from a US supplier without telling them this needs to be a 
220V country. As a result, I got an external power supply that is 110V, 
which outputs 12V AC at 1000mA (why they do not write "1A", I do not know).

To my shame, I actually bought a universal DC supply without noticing 
that it's AC I need, and started a support call with the company. They 
were very nice, and when we, finally, found out the source (I hope it is 
it), the guy said I could probably get by with 18VDC, but it would 
strain the capacitors (my math suggests that 15VDC is closer to the mark).

So, does anyone know where I can get a 12V AC power supply? They are not 
exactly a commodity.

Thanks,
Shachar
