I just purchased a wonderful YB 400 International; great radio
for the price.

I tried to use a wall-cube PS (stabilized, well filtered) but
I get strong interferences on some SW band caused by it; with batteries
all is fine.

I was wondering where I can buy (online) a power supply (wall-cube)
particullary suitable to power SW receivers.

Thanks in advance

PS: my apologies for my very little english.
