Anyway, mine has a built-in PSU. Just an IEC plug on
the back ('kettle
plug') that, in my case, takes in 240V AC. I guess they were made with
different transformers for other voltages.
It would appear that mine does as well. I never looked at it closely,
since it looked like a brick or wall-wart was supposed to fit into the
styrofoam packing. I guess nothing went there.
According to the schematic, the transformer has a
single secondary
winding (no taps). The AC from that is rectified, smoothed, and then
regulated down to a couple of 5V rails by a linear regulator circuit.
I would guess that the secondary gives about 8 to 9 VAC. If you
insist, I'll try to find my 1520 and measure it.
Thanks for the offer, but I thought it needed a wall-wart or something,
which is what I wanted to know the output voltage of.
