Be advised that all 516F-2's are not alike. Some earlier, winged units
were for 110v VAC ONLY and did not have split primaries. Be sure and
check before buying, if you need 220v.

I'd like to buy a 75S-3A or 75S3C Collins receiver. On eBay many are on sale
from USA suppliers.
I'm just in doubt because i cannot find clear indication on main power
supply possibilities.
Documentation found on Internet sometimes specify 110/220, other times just
110.
And i need a 220 capable unit, since i'm living in Europe.
Is there a way to detect clearly what is the effective power supply
installed?
I've the same problem also on the 516F-2 power supply.
The only power supply that clearly specify a dual voltage option is the
PM-2.
Is there somebody that can clarify my doubt?
Many thanks.
