Hi Rich,
I have a couple of US and Jap transformers from these guys...

This is the 100VA (100W) 120Volt version which should be suitable for your needs, but check the Wattage requirements on the player first

They are hand built silent toroidal transformers, and do a great job for my D-Theater players. I also have the 100V Jap version for my HLD-X9 laserdisc player, which they custom built, and then put on the web site for general sale!!
A great company to deal with. The main thing to bear in mind, is that you need good head room with transformers, ie. my D-Theater player draws 46 Watts, and the transformer above can supply 100 Watts. If you go for a cheapy 50W transformer, it will likely burn out, and can damage the player too.
Find out how many watts the player draws, and start from there.
Hope this helps.
Cheers, Lee
