Re: Silver box with a heatsink and a 33-45 switch
With a US input and output socket and a 240:120 converter and "over here" it sounds more like a converter for a US 60Hz deck over here than t'other way about.
All that heatsinking suggests a few watts of output.
Plug it all in and see what comes out of the socket- beware it may not be mains isolated!
