single phase reg/rect replacement

[hmmmnz]

does any one know where i can get a reg/rect as a replacement for my seperate bridge rectifier and zenar diode regulator,
its for a cb250g5
the wattage output of the alternator is 130w @ 5000rpm

or does any one know of any bikes that run a single phase alternator with a single unit reg/rect that i can look out for on ebay

cheers
